Sometimes, you just need a warm, comforting casserole at the end of a long day. This tuna casserole recipe is the perfect make-ahead dish!

Servings 8

Ingredients

  • 500 grams pasta
  • 1/3 cup salted butter
  • 1/4 cup flour
  • 1 onion diced
  • 1 clove garlic minced or pressed
  • 2 cups milk 2% or whole
  • 2 cups chicken broth
  • 3 cups of fresh broccoli florets or any other raw vegetable you’d like
  • 4 oz cheese of any type - I use 2oz each of cheddar and parmesan
  • 4 small cans or 2 large cans of tuna drained - I use Italian-style in olive oil

Instructions

  1. Preheat oven to 350F.

Pasta

  1. Set a large pot of water on high heat and add pasta. Cook until pasta is barely al dente (it will cook more in the oven). When pasta is ready, remove from heat and plunge broccoli into the water with the pasta. Drain pasta and broccoli together, place back into the pot and add drained tuna.

Sauce

  1. While the pasta is boiling, heat the butter in a medium saucepan, then add the onions and garlic.
  2. Cook onions and garlic until soft, around 2-3 minutes, then add flour and stir to coat
  3. Add broth and milk to the saucepan and, whisking constantly, bring to a slow boil until mixture thickens.
  4. Remove from heat and add the cheeses, stirring to melt.
  5. Pour the sauce over the pasta mixture and stir well to combine.
  6. Place pasta and sauce mixture into a casserole dish or cast iron pan, and sprinkle with parmesan.
  7. Bake at 350F for 30 minutes.
