Ingredients
- Shrimp: Use 1 pound of peeled and deveined shrimp for quick cooking and a tender, flavorful protein.
- Cauliflower: One large head cut into florets forms the base for creamy, low-carb “grits.”
- Heavy Cream: 1 cup adds richness and smoothness to the cauliflower mash.
- Shredded Cheddar Cheese: 1 cup to top the casserole for a gooey, golden finish.
- Cream Cheese: 1/4 cup softened cream cheese enhances creaminess and texture in the cauliflower mixture.
- Garlic: 2 cloves minced for aromatic depth and a subtle kick.
- Cajun Seasoning: 1 teaspoon imparts bold, spicy Southern flavor to the shrimp.
- Salt and Pepper: To taste, balancing and enhancing the overall flavors.
- Olive Oil: 2 tablespoons for sautéing shrimp and garlic, adding richness.
- Green Onions: Optional garnish providing freshness and mild onion flavor.
Instructions
- Preheat the Oven
-
Set your oven to 375°F (190°C) so it reaches the ideal temperature while you prepare the ingredients. This ensures the casserole bakes evenly and the cheese melts perfectly at the end.
- Cook the Cauliflower
-
Steam or boil the cauliflower florets for 5-7 minutes until tender. Cooking the cauliflower until soft is crucial for blending it into a smooth, creamy texture resembling traditional grits.
- Make the Cauliflower Grits
-
Drain the cooked cauliflower thoroughly to avoid watery grits. Blend the cauliflower with heavy cream, softened cream cheese, salt, and pepper until ultra smooth and creamy. This mixture acts as the comforting base of the casserole.
- Sauté Shrimp with Cajun Seasoning
-
Heat olive oil in a skillet over medium heat, then add minced garlic and shrimp. Cook shrimp until they turn pink and opaque, around 3-4 minutes, stirring occasionally. Season with Cajun seasoning, salt, and pepper to infuse bold, spicy flavors.
- Assemble the Casserole
-
Grease a 9×13-inch baking dish lightly. Spread the creamy cauliflower grits evenly on the bottom, then layer the spicy shrimp mixture on top. Finish by sprinkling shredded cheddar cheese to create a melted, golden crust after baking.
- Bake to Perfection
-
Place the casserole in the oven and bake for 20-25 minutes or until the cheese is bubbly and slightly browned. Baking brings all the flavors together and adds a delicious cheesy finish.
- Garnish and Serve
-
Remove the casserole from the oven and let it cool slightly. Garnish with chopped green onions for a fresh, vibrant touch that complements the richness of the dish before serving.
- Make sure to drain the cauliflower very well before blending to avoid watery grits.
- Adjust Cajun seasoning to your heat preference—start small and add more if desired.
- Use fresh shrimp for the best texture, but frozen, thawed shrimp also work well.
Storage Tips
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to retain creaminess and flavor without drying out.
Serving Suggestions
This casserole pairs beautifully with a crisp green salad or steamed low-carb vegetables for a complete keto meal. A squeeze of fresh lemon over the shrimp adds a delightful brightness.
- For extra creaminess, add a tablespoon of butter to the cauliflower blend before baking.
- Use a food processor for smoother cauliflower grits and less texture.
- Freshly shredded cheese melts better than pre-shredded varieties due to the lack of anti-caking agents.
FAQs
- Can I use frozen cauliflower instead of fresh?
-
Yes, frozen cauliflower can be used. Just thaw and drain it well before cooking to avoid excess moisture in the grits.

Full-fat coconut milk or unsweetened almond milk can be alternatives, but heavy cream provides the richest, creamiest texture.

-
This recipe is keto-friendly but not compliant with whole30 or paleo due to dairy and seasoning additives.
- Can I make this casserole ahead of time?
-

- How spicy is the Cajun seasoning in this dish?
-
The heat level depends on brand and amount used. You can reduce or omit it for a milder flavor.
- What can I use instead of cheddar cheese?

Monterey Jack or mozzarella can be good substitutes if you want a different melting cheese with a mild taste.
