How to Make Shrimp Casserole Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 350°F (175°C), so it’s ready when you finish prepping. Grease your baking dish with butter or nonstick spray to prevent sticking and help create a golden crust during baking.
Step 2: Sauté Your Veggies
In a large skillet, melt the butter over medium heat, then add the onion, garlic, bell pepper, and celery. Let them cook for about 5 minutes until they become soft and fragrant. This step builds the flavor foundation, inviting your kitchen to fill with a delicious aroma.
Step 3: Cook the Shrimp
Add the shrimp to the skillet with your sautéed veggies and cook for 2 to 3 minutes until they turn a lovely pink. Be careful not to overcook here because the shrimp will cook a little more in the oven. Once done, remove the skillet from heat.
Step 4: Combine the Base Ingredients
In a large bowl, mix together the cooked rice, cheddar cheese, Parmesan cheese, milk, heavy cream, sour cream, and all the seasonings: Old Bay, paprika, salt, pepper, thyme, and oregano. This combination creates a creamy, flavorful sauce that will coat every bite.
Step 5: Mix Shrimp and Veggies into the Base
Stir in the cooked shrimp and vegetables from the skillet into the creamy mixture. The colors and textures start coming together, promising something really tasty ahead.
Step 6: Transfer and Top
Pour the entire shrimp and rice mixture into your prepared baking dish. If you want that satisfying crunch, sprinkle breadcrumbs evenly over the top—this step is totally optional but highly recommended!
Step 7: Bake Until Bubbly and Golden
Place your casserole in the oven for 25 to 30 minutes. You’ll know it’s ready when the sauce is bubbling around the edges and the top is a beautiful golden brown. This creates a delightful contrast between creamy filling and crisp topping.
Step 8: Garnish and Serve
Just before serving, sprinkle chopped parsley on top for a fresh punch of color and flavor. Now your Shrimp Casserole Recipe is ready to impress.

Garnishes
Beyond the chopped parsley, consider a light squeeze of lemon juice or a few extra sprigs of fresh herbs like dill or chives. These will add a bright freshness that complements the richness beautifully.

What if I don’t have Old Bay seasoning?
No worries! Use a combination of paprika, celery salt, and a pinch of cayenne pepper to mimic that classic seafood spice blend.
