Recipe Variations

One of the best things about this recipe is its versatility. You can vary the ingredients and really make it your own. Here are a few suggestions:

  • Soup: Vary the soup. Instead of cream of mushroom, go for cream of shrimp.
  • Vegetables: Add other veggies, such as chopped carrots, peas, diced tomatoes, or corn. Swap the green bell pepper with red bell peppers for a pop of color.
  • Rice: For this shrimp casserole with rice, you can easily choose brown rice or wild rice in place of white rice.
  • Shrimp Casserole With Pasta: Instead of rice, you could use cooked noodles or pasta such as large wide egg noodles, penne, elbow macaroni, or shells.
  • Shrimp Casserole With Potatoes: Another idea is to use cooked, crispy potato wedges.

Note: If you choose a substitute for the rice, avoid anything that may be too soft. You need ingredients with some body to complement the creamy seafood layer.

  • Seafood Casserole: Add pretty much any seafood you like, and it will always turn out well. Go for a combination of succulent shrimp, sea scallops, crab meat, lobster meat, calamari, or fish. Seafood casserole is a big catch for your dinner table!
  • Chicken and Shrimp Casserole: Combine shrimp and chicken.
  • Spicy Shrimp Casserole – Add some cajun seasoning or cayenne pepper.
  • Topping – Instead of lemon slices, drizzle lemon juice over the casserole and top with breadcrumbs mixed with a little melted butter. Mixing in some parmesan cheese with the breadcrumbs would be good too.

Shrimp Casserole With Rice – Tips to Save Time

  • Buying peeled and deveined shrimp saves a ton of time.
  • Use precooked rice that comes in a pouch.
  • Buy a frozen seasoning blend consisting of a “trinity” of onion, bell pepper, and celery. See the recipe below if you would like to make your own seasoning blend.

Homemade Seasoning Blend

Many recipes call for a “seasoning blend”, which is a blend of onions, green pepper, and celery. Some grocery stores carry a nicely proportioned bag of this seasoning blend in the freezer section. However, you can make it yourself and keep several quart-sized bags in your freezer that you can pull out as needed. 

Seasoning Blend Ingredients

  • 2 cups bell pepper, chopped
  • 2 cups celery, chopped
  • 2 cups onion, chopped

Seasoning Blend Instructions

  1. Toss 2 cups of the seasoning blend into each of 3 quart-sized freezer bags.
  2. Flatten the bags out and place them in the freezer lying flat. Once frozen, they can be stacked upright. 
  3. This seasoning mix recipe is about equal parts of all 3 vegetables, but you can choose to add or subtract amounts or add other ingredients to fit your taste buds.

What to Serve With This Cheesy Shrimp Casserole With Rice

It’s a good idea to stick with sides that have a crunch or freshness to them, so they balance well with the rich flavors of the shrimp casserole. Here are some ideas:

How to Store Shrimp Casserole Leftovers

Fridge: Leftovers can be stored in your refrigerator in an airtight container for up to 4 days. 

Freezer: Wrap leftovers tightly with plastic wrap or place them in a freezer-safe container. Seafood casserole will keep in the freezer for up to 3 months.

Reheating: Using your oven is best for a dish containing shrimp. What you have to be most cautious about is the oven’s potential to dry your shrimp out. Follow these steps for the best results:

  1. Thaw the leftovers in the refrigerator overnight.
  2. Preheat your oven to 300°F. 
  3. Cover your pan or dish with aluminum foil and bake for about 15 minutes. The trick here is to use a low temperature, so you don’t overcook your shrimp.

Warning: If you use a glass casserole dish, taking the dish straight from the fridge to the oven can cause the container to break from temperature shock.

    I used uncooked shrimp. I placed the shrimp immediately into the hot cooked rice to get them started cooking. This will prevent the shrimp from getting over cooked while baking. The key to this great recipe is the hint of the lemon.
