Why This Recipe Works for Keto

The ketogenic diet relies on high fat, moderate protein, and very low carbohydrates. Seafood, particularly shrimp, is an excellent source of protein with zero carbs. However, shrimp is naturally lean. To make it “keto-perfect,” we need to add healthy fats. This recipe accomplishes that by incorporating:

• Heavy Whipping Cream: Provides a rich, creamy base with negligible carbs.
• Butter: Adds flavor and essential fats.
• Cheese (Mozzarella & Parmesan): Offers calcium, protein, and fat, creating that gooey texture we all crave.

By combining lean protein with these high-fat elements, you create a macronutrient profile that keeps you in ketosis while keeping you full for hours. Unlike starchy casseroles that cause blood sugar spikes and crashes, this meal provides sustained energy.

Ingredients

The beauty of this dish lies in its simplicity. You don’t need obscure ingredients; just fresh, high-quality staples.

The Seafood Base

• 1 lb Large Shrimp: Raw, peeled, and deveined. Tails on or off depending on preference (tails on look prettier, tails off are easier to eat).
• 1 tbsp Lemon Juice: Freshly squeezed is best to cut through the richness of the cheese.

The Creamy Garlic Sauce

• 4 tbsp Unsalted Butter: Divided use.
• 3 cloves Garlic: Minced finely. Fresh garlic is superior to jarred for this recipe.
• ½ cup Heavy Whipping Cream: This forms the base of your sauce.
• ¼ cup Chicken or Vegetable Broth: To lighten the sauce slightly and add depth.
• ½ tsp Onion Powder: For savory depth.
• ½ tsp Dried Oregano or Italian Seasoning: Adds an herbal note.
• Salt and Black Pepper: To taste.
• ¼ tsp Red Pepper Flakes: (Optional) For a gentle heat kick.

The Cheesy Topping

• 1 cup Mozzarella Cheese: Shredded. Buy a block and shred it yourself for better melting (pre-shredded contains anti-caking agents that add carbs).
• ½ cup Parmesan Cheese: Grated. Adds a salty, nutty bite.
• 1 tbsp Fresh Parsley or Thyme: Chopped, for garnish.

Step-by-Step Instructions

Follow these steps to ensure your shrimp remains tender and your cheese is perfectly browned.

1. Preheat and Prep
Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish or casserole pan (approx. 9×9 inch or oval baker) with a little butter or olive oil spray. Pat your shrimp dry with paper towels—removing excess moisture ensures they roast rather than steam.

2. Sear the Shrimp (Optional but Recommended)
While you can put raw shrimp directly into the oven, a quick sear adds flavor. Melt 1 tablespoon of butter in a skillet over medium-high heat. Add the shrimp and cook for just 1 minute per side until they turn pink but aren’t fully cooked. Transfer them to your baking dish.

3. Create the Garlic Butter Base
In the same skillet (don’t wash it, save that flavor!), add the remaining 3 tablespoons of butter. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant. Be careful not to burn the garlic.

4. Build the Cream Sauce
Lower the heat to medium. Pour in the heavy cream and chicken broth. Stir in the onion powder, oregano, salt, pepper, and red pepper flakes. Let the mixture simmer gently for 2–3 minutes until it thickens slightly. Stir in half of the parmesan cheese to thicken it further.

5. Combine and Assemble
Pour the creamy garlic sauce over the shrimp in the baking dish. Toss gently to ensure every shrimp is coated in the liquid gold.

6. The Cheesy Layer
Sprinkle the shredded mozzarella and the remaining parmesan cheese evenly over the top of the shrimp and sauce.

7. Bake to Perfection
Place the dish in the preheated oven. Bake for 12–15 minutes. You are looking for the cheese to be fully melted and bubbly, and the shrimp to be cooked through (opaque).
Pro Tip: If you want a golden-brown crust, switch the oven to “Broil” for the last 1–2 minutes, watching closely to prevent burning.

8. Garnish and Serve
Remove from the oven and let it rest for 5 minutes (the sauce will thicken as it cools slightly). Garnish with fresh chopped parsley or thyme and a squeeze of lemon juice.

Tips for the Perfect Shrimp Bake

Avoid Rubber Shrimp:
Shrimp cooks very quickly. If you are using pre-cooked shrimp, reduce the baking time significantly—you are essentially just heating them up and melting the cheese. For the best texture, use raw shrimp.

Shred Your Own Cheese:
As mentioned in the ingredients, pre-bagged cheese is coated in potato starch or cellulose to prevent clumping. This adds unnecessary carbs and prevents the cheese from melting into a smooth, cohesive layer. Grating your own block of mozzarella takes two minutes and makes a world of difference.

Dry the Shrimp:
Water is the enemy of a thick sauce. Frozen shrimp releases a lot of water. If using frozen, thaw them completely and squeeze them gently in paper towels to remove as much water as possible before cooking.

Variations and Add-Ins

Cooking is about creativity. Here are a few ways to customize this bake while keeping it keto:

• Add Veggies: Stir in a handful of fresh spinach or blanched broccoli florets into the sauce before baking to add volume and nutrients. Asparagus tips also pair wonderfully with the garlic cream sauce.
• Make it Spicy: Increase the red pepper flakes or add a teaspoon of Cajun seasoning to the sauce for a “New Orleans” style kick.
• Surf and Turf: Add cooked, crumbled bacon or sliced keto-friendly sausage (like Andouille) to the bake for a smoky, meaty flavor profile.
• Crispy Topping: If you miss the crunch of breadcrumbs, crush up some pork rinds or use a mixture of almond flour and parmesan cheese to sprinkle on top before baking.

Serving Suggestions

While this dish is rich enough to stand on its own, balancing it with a side can make for a more complete meal. Here are the best low-carb pairings:

• Cauliflower Rice: The sauce from the shrimp acts as a perfect gravy for roasted or steamed cauliflower rice.
• Zucchini Noodles (Zoodles): Serve the shrimp and sauce over a bed of spiralized zucchini for a “pasta” night experience.
• Steamed Green Beans: The crunch of green beans contrasts perfectly with the soft, creamy shrimp.
• Keto Garlic Bread: Use an almond flour-based bread recipe to sop up the remaining garlic butter sauce.

Storage and Reheating

Storage:
Store leftovers in an airtight container in the refrigerator for up to 3 days. Seafood is best consumed fresh, so try to eat it sooner rather than later.

Reheating:
Microwaving seafood can lead to a rubbery texture. The best way to reheat this dish is in the oven at 350°F for about 10 minutes, or in a skillet on the stovetop over low heat until warm. If the sauce has separated, a splash of water or heavy cream while reheating can bring it back together.
