Wholesome Ingredients for This Creamy Shrimp and Crab Casserole

This casserole relies on fresh, wholesome ingredients to deliver maximum flavor and nutrition. Here are some of the key players:

• Shrimp: Shrimp isn’t just a low-calorie protein powerhouse; it’s also rich in selenium, an essential mineral for immune health. For the best flavor, use wild-caught shrimp and peel and devein them yourself.
• Crabmeat: Crab offers a sweet, ocean-fresh flavor while delivering omega-3s and vitamin B12. Opt for lump or claw meat for a meatier texture.
• Vegetables (Onion, Celery, Green Pepper): These form a traditional Louisiana “holy trinity” base, bringing natural sweetness, aromatics, and crunch to the dish. Swap in carrots or mushrooms for variety.
• Cream Cheese and Cheddar Cheese: Essential for that creamy, dreamy texture without needing heavy cream. If you’re looking to reduce calories, choose reduced-fat cheese options.
