Warm Introduction
There are certain meals that instantly feel like a reward. Not because they’re fancy or complicated, but because they hit that perfect balance between comfort and nourishment. This Keto Shrimp & Cheese Casserole is one of those dishes for me. I still remember the first time I made it on a quiet evening after a long, mentally draining day — the kind where you want something warm, creamy, and satisfying, but you don’t want to undo all the good choices you’ve made that week. The aroma of garlic, butter, and melted cheese filled the kitchen, and before the casserole even came out of the oven, I knew it was going to be a repeat recipe.
What makes this keto shrimp & cheese casserole special is how effortlessly it fits into a low-carb lifestyle without feeling restrictive. Shrimp cooks quickly, absorbs flavor beautifully, and pairs incredibly well with creamy cheeses and subtle seasoning. Combined into a casserole, it becomes a cozy, spoon-worthy dinner that feels indulgent but keeps carbs low and protein high. Whether you’re fully keto, eating low-carb for blood sugar balance, or simply trying to get more protein-rich meals on the table, this dish checks every box.
Over time, this casserole has become one of my go-to “reset meals.” It’s the kind of dinner I make when I want something grounding — when salads feel too light and heavy comfort food feels like too much. It’s creamy without being greasy, filling without being heavy, and satisfying in a way that makes you slow down and actually enjoy your meal. That’s what real healthy eating should feel like.
What Makes This Keto Shrimp & Cheese Casserole Stand Out
Most low-carb casseroles lean heavily on meat and cheese, sometimes at the expense of balance or texture. What sets this keto shrimp & cheese casserole apart is how thoughtfully each element plays its role. Shrimp brings lean, high-quality protein and a naturally sweet flavor that contrasts beautifully with savory cheeses. Instead of masking the shrimp, the creamy base enhances it.
Another standout feature is how quickly this recipe comes together. Shrimp doesn’t require long cooking times, and there’s no breading, no complicated layering, and no pre-cooking multiple components separately. Everything flows naturally from skillet to baking dish, making this a realistic weeknight dinner, not just a weekend project.
From a nutrition standpoint, this casserole is incredibly supportive of keto and low-carb goals. It’s rich in healthy fats, moderate in protein, and naturally low in carbohydrates without relying on specialty ingredients. That makes it approachable, budget-friendly, and easy to adapt depending on what you already have in your fridge.
Finally, there’s the versatility factor. This dish works equally well as a cozy family dinner, a meal-prep staple, or even a crowd-pleasing option for guests who aren’t keto at all. No one ever complains that it’s “diet food” — and that’s always a good sign.
Personal Blogger Note
The first time I tested this recipe, I actually wasn’t planning on writing it down. It was one of those “use what’s in the fridge” nights — a bag of shrimp, a couple of cheese odds and ends, and some cream that needed to be used. But halfway through cooking, I could tell it was something special. The shrimp stayed tender, the sauce thickened beautifully, and the cheese melted into that perfect, silky texture that coats the spoon.
I’ve made this casserole many times since, tweaking small details depending on my mood. Some nights I keep it very simple and let the shrimp shine. Other times I add subtle herbs or a hint of garlic butter when I want something extra comforting. Every version has worked, which tells me the foundation of the recipe is solid.
What I love most is how this dish makes keto feel sustainable. It doesn’t feel like a “swap” or a compromise. It feels like a meal you’d make anyway — rich, warm, and deeply satisfying — that just happens to be low-carb. Those are the kinds of recipes that stick, and that’s exactly why this one earned a permanent place in my rotation.
Kitchen Equipment You’ll Need (And Why It Matters)
A large skillet is essential for this recipe because shrimp cooks best when it has enough surface area. Crowding shrimp causes steaming instead of searing, which affects texture and flavor. A roomy skillet allows each piece to cook evenly and develop a light golden edge before going into the casserole.
You’ll also need a mixing bowl for combining the creamy cheese base. This helps you fully incorporate ingredients without overworking them in the hot pan, which can cause separation in dairy-based sauces.
A baking dish is where everything comes together. I prefer a medium-sized dish that allows the casserole to spread out slightly rather than being piled too thick. This ensures even baking and a better ratio of shrimp to sauce in every bite.
A silicone spatula or wooden spoon is ideal for stirring. These tools are gentle on shrimp and help you fold ingredients together without breaking them apart.
Finally, having a measuring cup and spoons nearby ensures consistency. Keto recipes rely heavily on balance — too much cream or cheese can overpower shrimp, while too little can leave the casserole dry.
Ingredients with Substitutions (Exact Measurements Included)
Shrimp (1½ pounds, peeled and deveined)
Shrimp is the protein star of this dish. It’s naturally low-carb, cooks quickly, and stays tender when handled gently. Medium to large shrimp work best. If using frozen shrimp, thaw completely and pat dry to avoid excess moisture.
Cream Cheese (8 oz, softened)
This forms the base of the sauce, adding richness and thickness. Softening it beforehand ensures a smooth texture. For a lighter option, part-skim cream cheese can be used, though full-fat gives the best mouthfeel.
Heavy Cream (¾ cup)
Heavy cream creates a silky, luxurious sauce and helps keep the casserole keto-friendly. Coconut cream can be used for a dairy-free variation, though it will slightly alter flavor.
Shredded Mozzarella Cheese (1½ cups)
Mozzarella melts beautifully and provides that classic cheesy stretch. Monterey Jack or provolone are good substitutes if needed.
Grated Parmesan Cheese (½ cup)
Parmesan adds depth and a subtle salty bite that balances the creaminess. It also helps the top brown lightly in the oven.
Butter (2 tablespoons)
Butter enhances flavor and helps sauté the shrimp gently. Ghee can be used as a lactose-free alternative.
Garlic (3 cloves, minced)
Fresh garlic brings aroma and savory warmth. Garlic powder can be substituted in a pinch, but fresh gives better flavor.
Salt (¾ teaspoon, or to taste)
Salt enhances all the flavors, especially shrimp and cheese.
Black Pepper (½ teaspoon)
Adds subtle heat and balance.
Paprika (½ teaspoon, optional)
Paprika adds gentle warmth and color without adding heat.
Step-by-Step Cooking Process
Preparing the Shrimp for Maximum Flavor
Before any heat touches the pan, take a moment to prepare the shrimp properly. Pat the shrimp completely dry using paper towels. This step matters more than most people realize. Excess moisture prevents shrimp from developing flavor and can water down the casserole later. Once dry, lightly season the shrimp with salt, black pepper, and paprika. This early seasoning ensures the shrimp itself tastes good, not just the sauce around it.
Sautéing the Shrimp Gently
Heat a large skillet over medium heat and add the butter. Allow it to melt fully but not brown. Add the shrimp in a single layer and let them cook undisturbed for about 1–2 minutes per side, just until they turn pink and opaque. Do not overcook here. Shrimp continues cooking in the oven, and overcooking at this stage leads to rubbery texture later. Remove the shrimp from the skillet and set aside.
Building the Creamy Cheese Base
In the same skillet, lower the heat slightly and add the minced garlic. Stir gently for about 30 seconds, just until fragrant. Add the softened cream cheese and stir slowly until it begins to melt and smooth out. This step requires patience. Keep the heat low and stir constantly to avoid scorching.
Once the cream cheese is mostly smooth, pour in the heavy cream gradually while stirring. The sauce will look thin at first, but as it warms and emulsifies, it becomes silky and cohesive. This is the foundation of your casserole, so take your time here.
Adding the Cheeses
Stir in the shredded mozzarella and grated parmesan, a little at a time. Allow each addition to melt fully before adding more. The sauce should become thick, creamy, and glossy. Taste at this stage and adjust seasoning if needed. Remember that parmesan adds saltiness, so go lightly.
Combining Everything Together
Gently fold the cooked shrimp back into the sauce, coating each piece evenly. Turn off the heat once everything is combined. You’re not trying to cook further here — just bringing all components together.
Baking Until Perfectly Creamy
Transfer the shrimp and cheese mixture into a lightly greased baking dish. Spread it evenly so the shrimp are distributed throughout the casserole rather than sinking to the bottom. Place the dish into a preheated oven at 375°F (190°C) and bake until the casserole is bubbling gently around the edges and lightly golden on top. This usually takes about 18–22 minutes.
Remove from the oven and let it rest for 5 minutes before serving. This resting time allows the sauce to thicken slightly and settle.
Health & Nutrition Insights
This keto shrimp & cheese casserole is an excellent example of how low-carb eating can still feel nourishing and satisfying. Shrimp is a lean protein source rich in iodine, selenium, and vitamin B12 — nutrients that support metabolism and energy levels. Combined with healthy fats from cream, butter, and cheese, this meal promotes satiety and stable blood sugar levels.
Because the recipe avoids starches, flours, and fillers, it keeps net carbs very low while still delivering comfort-food satisfaction. The fat-to-protein balance makes it especially suitable for keto, but it also works well for anyone following a low-carb or sugar-free lifestyle.
Serving & Pairing Ideas
This casserole is rich and creamy, so it pairs best with lighter sides. A crisp green salad with a lemony vinaigrette works beautifully to balance the richness. Steamed broccoli, sautéed zucchini, or roasted asparagus are excellent low-carb options.
For drinks, sparkling water with lemon or a lightly chilled herbal tea complements the dish without overwhelming it. This casserole also works well as a standalone meal — it’s filling enough on its own.
Storage & Meal Prep Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat or in the oven covered with foil to prevent drying out. Avoid microwaving on high, as it can cause the sauce to separate.
This casserole does not freeze particularly well due to the dairy content, which can change texture after thawing. It’s best enjoyed fresh or refrigerated short-term.
Frequently Asked Questions
Can I make this dairy-free?
You can substitute dairy-free cream cheese and coconut cream, but the flavor and texture will change. It will still be low-carb but less traditional.
Can I use pre-cooked shrimp?
It’s not recommended. Pre-cooked shrimp tends to become rubbery when baked again.
Is this recipe good for meal prep?
Yes, as long as you plan to eat it within a few days and reheat gently.
Can I add vegetables?
Yes. Spinach or mushrooms work well, but sauté them first to remove moisture.
Kitchen Tips & Troubleshooting
If the sauce looks too thick before baking, add a splash of cream to loosen it.
If it looks too thin, let it simmer gently for another minute before baking.
Always keep heat moderate when working with cheese to avoid separation.

Keto Shrimp & Cheese Casserole Recipe
Ingredients
Method
- Begin by patting the shrimp completely dry with paper towels. This step is crucial because removing excess moisture allows the shrimp to develop better flavor and prevents the casserole from becoming watery. Once dry, season the shrimp lightly with salt, black pepper, and paprika, tossing gently so each piece is evenly coated without overpowering the natural sweetness of the shrimp.
- Place a large skillet over medium heat and add the butter. Let it melt fully but do not allow it to brown. Add the shrimp in a single layer and cook for about 1–2 minutes per side, just until they turn pink and opaque. Avoid overcooking at this stage, as the shrimp will finish cooking in the oven. Remove the shrimp from the skillet and set them aside on a plate.
- Lower the heat slightly and, using the same skillet, add the minced garlic. Stir gently for about 20–30 seconds, just until fragrant. Keep a close eye on it, as garlic can burn quickly and turn bitter if cooked too long.
- Add the cream cheese to the skillet and stir slowly as it begins to soften. Keep the heat low and be patient, stirring continuously to help it melt evenly and become smooth without sticking or scorching on the bottom of the pan.
- Gradually pour in the heavy cream while stirring constantly. At first, the mixture may look thin or slightly separated, but continue stirring gently. As it warms, the sauce will come together into a smooth, cohesive, and silky base.
- Add the shredded mozzarella and grated parmesan cheese a little at a time, stirring after each addition until fully melted. The sauce should become thick, creamy, and glossy. Taste at this stage and adjust seasoning if needed, keeping in mind that parmesan adds saltiness.
- Gently fold the cooked shrimp back into the cheese sauce, making sure each piece is well coated. Once combined, turn off the heat. You’re simply bringing everything together here, not cooking further.
- Transfer the shrimp and cheese mixture into a lightly greased baking dish. Use a spatula to spread it out evenly so the shrimp are distributed throughout the sauce rather than clustered in one area.
- Place the dish into a preheated oven set to 375°F (190°C) and bake until the casserole is bubbling gently around the edges and lightly golden on top. This usually takes about 18–22 minutes, depending on your oven.
- Remove the casserole from the oven and let it rest for about 5 minutes before serving. This short resting time allows the sauce to thicken slightly and settle, making the casserole easier to serve and even more satisfying to eat.
