Let’s talk about the kind of dinner that doesn’t just fill your belly but wraps you up like a cozy blanket on a chilly night. That’s exactly what Tuna Casserole does. It’s creamy, cheesy, and packed with flavor thanks to tender noodles, sharp cheddar, Gruyere, and that irresistible crunchy panko topping.

And let’s be honest: casseroles are basically the universal love language of comfort food. They’re nostalgic, they’re crowd‑pleasing, and they somehow manage to feel both rustic and elevated at the same time.

Ingredients

• NOODLES
• 16 oz. noodles of choice
• SAUCE
• 3 tablespoons butter
• 2 tablespoons olive oil, divided
• 1/3 cup flour
• 2 cups half and half
• 3 cups chicken broth
• 1 1/2 tablespoons cornstarch
• 1 1/2 teaspoons Dijon mustard
• 1 1/2 teaspoons Worcestershire sauce
• 3 teaspoons chicken bouillon
• 2 teaspoons salt
• 1 tsp EACH onion powder, garlic powder
• 1 teaspoon pepper
• 3 cups grated sharp cheddar cheese divided (or more to taste)
• 3 oz. freshly grated Gruyere cheese (1 packed cup)
• 1/2 cup sour cream
• 2 cans (7 oz. each) solid white albacore tuna drained
• 2 cups frozen peas thawed
• PANKO TOPPING
• 3/4 cup panko breadcrumbs
• 1 tablespoon melted butter
• 1 tablespoon extra virgin olive oil

Instructions

Cook the noodles in salted water until barely al dente, about 2 minutes less than packaging instructions.
PANKO: Meanwhile, melt 1 tablespoon butter in 1 tablespoon olive oil over medium heat in a nonstick skillet. Add panko and stir to coat. Continue cooking until crumbs become golden brown. Transfer to a plate; set aside.
Preheat oven to 350 degrees F. Lightly spray a 9x13 pan with nonstick cooking spray.
Melt butter with olive oil in a very large skillet or Dutch oven medium heat (something that can fit all ingredients). Whisk in flour then cook, while stirring for 2 minutes. Turn heat to low then gradually whisk in milk and 1 ½ cups chicken broth. Whisk cornstarch with remaining chicken broth and add to skillet followed by Dijon, Worcestershire sauce, chicken bouillon and all spices/seasonings.
Bring sauce to a boil, whisking constantly then reduce heat to a simmer, whisking often until thickened. Remove from heat and whisk in 1 cup cheddar until melted followed by Gruyere cheese until melted. Whisk in sour cream until blended.
Add the tuna and peas and stir to combine. Stir in the noodles until evenly combined. If the sauce has become too thick add a little more chicken broth. Pour into the prepared baking dish and top with remaining 1 cup cheddar cheese followed by panko.
Cover with foil and bake at 350 degrees for 30 minutes, uncover and bake an addition 10-15 minutes or until hot and bubbly and cheese is melted; serve piping hot.
