Shrimp and Cauliflower Rice Casserole

Sharing is caring!

I love just about anything with shrimp. And rice. And cheese. And in a casserole dish. This is a delicious shrimp and cauliflower rice casserole, similar to shrimp and grits, but with a twist. I’m from the South and spent some time living in Louisiana, so eating shrimp and grits is almost a requirement.

I love to try different easy keto cauliflower recipes. I’ve made this keto and low carb friendly. It’s rich, so, if that’s you, be sure to track with your macros. When I’m not trying to make it low carb, I’ll sub grits or real rice for the cauli rice. If it seems too rich, You can use light versions of the cheeses.

You do you!

Ingredients for Shrimp and Cauliflower Rice Casserole

Onion and peppers – chop chop! I only used 1/2 of each, so maybe consider doubling the batch if you want to use the whole veggie. Double it? You won’t be disappointed.

Then sauté peppers, onions and the shrimp in a sauce pan. Determining the right time to add the shrimp depends on whether or not they are pre-cooked. Mine were, so I added them at the very end. You’ll have some baking time too, so you won’t want to overcook. Add the liquid ingredients and simmer until blended. It doesn’t need to thicken too much.

Since I’m originally from the Eastern Shore of Maryland, shrimp was always bathed in Old Bay. In fact, if you didn’t leave the table with your fingers burning from spice, you didn’t enjoy your meal enough. I didn’t add Old Bay to this recipe, but I might try that next!

Layer the cauliflower rice in a baking dish, top with the shrimp mixture and cheese. It’s all that simple.

Low Carb Shrimp and Grits?

Truth be told, I created this dish looking for a low carb option for shrimp and grits. I’d seen many recipes for shrimp and (cauli) grits, but I have to say, the cauli taste was quite present, so the idea that these were a grits substitute didn’t quite stick.

Whenever I read a recipe written like this one, I really wonder whether I should try it or skip it. I mean, who buys shrimp by the cup?

Shrimp and grits usually has bacon and scallions. Have you tried adding these ?
