Ingredients

  • 2 cans or 1 lb. fresh shrimp
  • 1/2 c. green pepper, finely chopped
  • 1/2 c. onion, finely chopped
  • 1/2 c. pimento, finely cut
  • 1 c. chopped celery
  • 1 (4 oz.) can mushroom stems and pieces
  • 1 c. mayonnaise
  • 1/2 tsp. salt
  • 1 c. half and half
  • 1/8 tsp. pepper
  • 1 Tbsp. Worcestershire sauce

Instructions

  1. Mix all ingredients except 3/4 cup cheese together.
  2. Place the mixture in a 2-quart casserole dish.
  3. Sprinkle with the remaining cheese on top.
  4. Bake at 375°F for 30 minutes.

Tips & Substitutions

For added flavor, consider substituting the mayonnaise with Greek yogurt for a lighter option. You can also use cooked crabmeat instead of shrimp for a different seafood twist. When chopping vegetables, make sure they are finely chopped to ensure even cooking. If you prefer a bit of spice, add a dash of hot sauce to the mixture. This dish pairs beautifully with Traditional Maryland Oyster Stew.

Serving Suggestions

Serve the Baked Shrimp Casserole with a fresh green salad or steamed vegetables for a balanced meal. It also pairs nicely with a side of rice or crusty bread for soaking up the creamy sauce. Consider serving it alongside Cajun Rush's Chargrilled Shrimp for a seafood-themed dinner.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in the oven at 350°F until warmed through, about 20 minutes. You can also microwave individual portions, but be careful not to overcook, as this can make the shrimp tough.

Frequently Asked Questions

Can I use frozen shrimp for this recipe?

Yes, you can use frozen shrimp. Just ensure they are thawed and drained well before mixing them into the casserole. This will help maintain the right texture and prevent excess moisture in the dish.

What can I substitute for half and half?

If you don't have half and half, you can mix equal parts of whole milk and heavy cream as a substitute. Alternatively, you can use a dairy-free cream or a combination of almond milk and coconut cream for a lighter option.

Can I prepare this casserole ahead of time?

Absolutely! You can prepare the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. Just add a few extra minutes to the baking time if it's coming straight from the fridge.
