a brief intro to shrimp and grits:

Shrimp and grits is a classic dish in Southern coastal cuisine which features a creamy ground corn porridge that resembles polenta.

Although the true birthplace of shrimp and grits is thought to be Charleston, South Carolina, it has since gained widespread popularity. This dish was even declared the official state food of South Carolina in 1976.

Initially intended as a breakfast dish for fishermen, it has evolved to become a favorite option for lunch, brunch, and dinner across the Southern United States. Here’s that classic combination in casserole form.

Why This Recipe is a Keeper!

Whether you’re hosting a family dinner or looking for a new comfort dish to enjoy, this shrimp and grits casserole hits all the right notes!

Before moving to the South 30 years ago, I never had grits, nor shrimp and grits. Frankly, grits scared me because I thought them to be bland and boring.

I finally tried them some years back when my husband and I stayed at an elegant bed-and-breakfast in Mississippi while taking the long way home from New Orleans. Breakfast was plated and served to all the guests and there they were in front of me: Grits.

Not boring at all, but creamy and delicious cheese grits!

After that day and after enjoying shrimp and grits at numerous restaurants if they’re on the menu, I’m now somewhat of a fanatic.

Recipe Ingredients:

Here’s everything you’ll need to make this shrimp and grits casserole recipe. The exact quantities are on the recipe card below.

Ingredient Notes and Substitutions:

Shrimp: It’s essential to always use wild-caught U. S. Gulf shrimp. They are much more resilient to reheating in a casserole, unlike farmed shrimp, which most certainly will become rubbery. I used 31-40 count, which is considered “medium-large.” You can use larger shrimp or smaller shrimp. However, I found the 31-40 count medium-large to be the right size–substantial, yet easy to manage on the plate.
Bacon: If you don’t consume pork, use turkey or beef bacon. You can also use diced andouille sausage.
Diced Tomatoes with Green Chiles: This shrimp and grits casserole recipe calls for a 10-ounce can such as Ro-Tel. You can substitute regular petite-diced tomatoes if you want to dial down the heat. Drain them well as the additional liquid could result in a soupy result.
Jalapeno: Use as little or as much as you wish. Removing the seeds will cut the heat if you want a milder casserole.
Quick Grits: Quick-cooking grits (not instant) work well in a casserole like this because of the other textures. Stone-ground grits will take much longer to cook, so cook them separately first, following the package directions, then add the vegetable combination and the remaining ingredients. I don’t recommend instant for this dish. They cook too fast and can turn mushy quickly.
Chicken Broth: Can also use fish stock.
Gouda Cheese: Gouda cheese melts beautifully and has a mild flavor, so it doesn’t compete with the shrimp. Smoked Gouda, Monterey Jack, or Pepperjack will also work well.
Cornstarch: Helps to thicken and reinforce the casserole’s structure without changing the flavor. Also keeps it gluten-free.

Step-By-Step Instructions:

Gather and prep all the ingredients.
Preheat the oven to 375 degrees.
Lightly grease a 1 1/2 – 2-quart baking dish with oil, butter or cooking spray. Set aside.

Cook the shrimp: Place a colander in the sink to drain the shrimp. Then, bring a large, heavy saucepan of well-salted water (about 2 teaspoons) to a boil. Turn off the heat, add the shrimp, and cook for 10 to 15 seconds, or until they turn pink, stirring once or twice. Drain immediately into the colander and cool quickly under cold tap water. Alternatively, prepare an ice bath and cool the shrimp in that. Drain the shrimp and pat dry.

In a heavy saucepan, cook the bacon over medium heat until browned and crispy. Transfer the bacon to a paper towel-lined plate with a slotted spoon, reserving the drippings in the saucepan.

Sprinkle with the remaining 1/2 cup cheese.

Bake for 30 to 35 minutes or until heated through and bubbling. The casserole should be set around the perimeter with an internal temperature of at least 165 degrees. Let stand 5 to 10 minutes before serving

Chef Tips and Tricks:

A shallow 1½ to 2-quart dish works best. Deep baking dishes take longer to set.
Nearly all commercial shrimp sold is individually quick-frozen. The shrimp sold in the seafood display case has likely been thawed. If purchasing thawed shrimp, be sure to use it within a day or two and don’t refreeze it. I prefer to purchase frozen shrimp and thaw it myself.
Be very careful not to overcook the shrimp. You don’t need to boil the shrimp; boil the water. Generously salt the water and get it to a rolling boil. Then, turn the heat off. Drop the shrimp into the water, stir it, and when the shrimp turns barely opaque (which happens quickly), remove it and cool it either under cold tap water or in an ice bath.
The grits should be thick and spoon-standing before anything else is added. Undercooking the grits can result in a soupy casserole. (See Step #6 and how the grits hold their form.)
Taste and season the grits with salt before adding the egg/cornstarch and remaining ingredients.
The egg/cornstarch must be added in a separate step, rather than mixing it in with the bacon, shrimp, and cheese, so it distributes evenly throughout the grits. This ensures even distribution and proper binding. It’s also essential to let the grits cool for 15 minutes before adding the egg. If you add it too quickly, the egg could scramble. This also gives the grits additional time to thicken up before the egg (which is liquid) is added.
Bake uncovered so excess moisture can evaporate. However, if the cheese browns too much, cover it loosely with aluminum foil.
Let the casserole rest for 5 to 10 minutes before serving so the grits firm up. The perimeter of the casserole should be set, with the interior remaining creamy.

Recipe FAQs:

can i use stone-ground grits instead of quick-cooking?

Yes. However, stone-ground grits require a much longer cooking time, so prepare them separately according to the package directions before incorporating the vegetable mixture and remaining ingredients.

do i have to cook the shrimp first?

Yes, I highly recommend it. Uncooked shrimp can create additional liquid, resulting in a soupy casserole. There is also a food safety concern. As long as you use wild-caught shrimp, don’t boil the shrimp, overcook it, and cool it promptly; it will hold up well to being reheated in the casserole.

do i have to add the egg?

Yes, I recommend it. I tested a batch of grits without the egg, and they were dense after baking.

why did my shrimp and grits casserole turn out soupy?

A shrimp and grits casserole can turn out soupy for several reasons:
>>The grits were not completely cooked, and the grits mixture was not thick enough.
>>There is too much liquid. Excess moisture from ingredients like shrimp, vegetables, or tomatoes can thin the mixture if they aren’t well-drained first. The typical ratio of quick grits to liquid is 1/4 cup of grits to 1 cup of liquid. This shrimp and grits casserole recipe uses 3/4 cup of grits to 2 cups of liquid, so the extra 1/4 cup of grits helps absorb any additional moisture released by the vegetables and shrimp.
>>The casserole was made ahead of time and covered before it completely cooled, allowing steam to drip back down onto the casserole.
>>The casserole was covered while baking.
>>The resting time was skipped. Letting the casserole sit for 10 to 15 minutes before serving allows the grits and eggs to finish firming up, often fixing what looks like a soupy texture straight out of the oven.

can i make this shrimp and grits casserole ahead of time?

Yes, it can be assembled 24 hours in advance. Let it cool completely before covering it for refrigeration so condensation doesn’t drip onto the casserole, which can make it soupy. Let it sit at room temperature for 30 minutes before placing it in the oven.
Bake uncovered so moisture can evaporate. Cover loosely if the cheese is starting to look brown. Baking time may be longer if the casserole is super cold from the refrigerator.

can i freeze this casserole?

Yes, cool uncovered, wrap securely, and freeze. Thaw in the refrigerator for at least 24 hours. Let the casserole sit at room temperature for 30 minutes or so before placing it in the oven.
Bake uncovered so moisture can evaporate. Cover loosely if the cheese is starting to look brown. Increase baking time if the casserole is super cold.
