Ingredients

• 1 can (10.5 ounces) Campbell’s® Condensed Cream of Mushroom Soup (or 98% Fat Free/Unsalted version)
• 1/2 cup milk
• 2 tablespoons chopped pimientos (optional, for color and flavor)
• 1 cup frozen green peas (about 4 1/2 ounces)
• 2 cans (about 5 ounces each) tuna in water, drained
• 2 cups cooked egg noodles (cooked al dente from about 4 ounces dry)
• 2 tablespoons plain dry bread crumbs
• 1 tablespoon butter, melted
• Salt and pepper, to taste

Instructions

1. Prepare the Oven & Base: Preheat the oven to 400°F. In a 1 1/2-quart casserole dish, combine the cream of mushroom soup, milk, pimientos (if using), peas, tuna, and cooked noodles. Season with salt and pepper, then mix until evenly coated.
2. Add the Topping: In a small bowl, stir together the bread crumbs and melted butter.
3. Bake the Casserole: Place the tuna mixture in the oven and bake uncovered for 20 minutes, or until hot and bubbling around the edges. Stir gently to mix.
4. Finish with Crunch: Sprinkle the buttered bread crumbs over the casserole. Return to the oven and bake for another 5 minutes, or until the topping is golden brown.
5. Serve & Enjoy: Let rest for a few minutes before serving warm.

Tips for Success

• Using Unsalted Soup: If using the unsalted cream of mushroom, add about 1/4 teaspoon of salt (or to taste).
• Swap the Veggies: No peas? Corn, carrots, or even mixed vegetables work well.
• Topping Options: If you don’t have bread crumbs, crushed crackers or even crispy fried onions make a great substitute.
• Make It Cheesy: Stir in 1/2 cup shredded cheddar or mozzarella for an extra creamy, cheesy version.

Serving Suggestions

This tuna casserole pairs perfectly with a crisp side salad or roasted vegetables for a balanced meal. Leftovers reheat beautifully, making it ideal for meal prep. It’s also freezer-friendly—just assemble, cover tightly, and freeze before baking.
