Ingredients
Instructions
- Reserve 1/4 cup of shredded Cheddar cheese for topping.
- Whisk cream of celery soup and milk in a 2-quart microwave-safe bowl until well blended.
- Stir in the drained water-pack tuna, uncooked elbow macaroni, frozen green peas, chopped onion, and the remaining Cheddar cheese (excluding the reserved cheese).
- Cover and refrigerate for at least 12 hours or overnight.
Tips & Substitutions
For a creamier texture, consider adding a dollop of sour cream or Greek yogurt to the mixture before refrigerating. You can substitute the elbow macaroni with any short pasta you have on hand. If you prefer a different flavor, try adding some garlic powder or a sprinkle of Italian seasoning. For a twist, incorporate some frozen corn or bell peppers for added color and nutrition.
Serving Suggestions
Serve this Overnight Tuna Casserole warm, garnished with the reserved shredded Cheddar cheese. It pairs beautifully with a crisp green salad or steamed vegetables for a well-rounded meal. For a heartier option, consider serving it alongside garlic bread or a side of roasted potatoes. To enhance the flavor, a drizzle of lemon juice can brighten the dish.
Storage & Reheating
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for about 1-2 minutes or until heated through. If reheating the whole casserole, cover with foil and bake at 350°F for about 20-25 minutes until warmed. You might want to sprinkle a little extra cheese on top before reheating for a delicious finish.

Frequently Asked Questions
Can I use fresh tuna instead of canned for this casserole?
Yes, you can use fresh tuna; however, you'll need to cook it first. Poach or grill the fresh tuna until fully cooked, then flake it before adding it to the casserole. This will provide a fresher taste and texture compared to canned tuna.
Can I make this casserole without pasta?
Absolutely! If you're looking to reduce carbs or make it gluten-free, you can omit the pasta and replace it with cooked quinoa or cauliflower rice. This will still provide a fulfilling dish while maintaining the flavor of the other ingredients.
How can I make this dish spicier?
To add some heat, consider mixing in diced jalapeños or a splash of hot sauce before refrigerating. You can also top the casserole with crushed red pepper flakes when serving for an extra kick. These additions will give your tuna casserole a flavorful twist.
