Ingredients

Original recipe (1X) yields 4 servings

  • 3 ¼ cups penne pasta

  • 1 tablespoon butter, or more to taste

  • 1 ½ cups sliced fresh mushrooms

  • 1 onion, finely chopped

  • 1 tablespoon all-purpose flour

  • 1 ¼ cups milk

  • ½ cup frozen peas

  • ½ cup frozen sweet corn

  • 1 (7 ounce) can tuna, drained

  • ½ (8 ounce) package shredded Cheddar cheese

Directions

  1. Bring a large pot of lightly salted water to a boil. Add penne and cook, stirring occasionally, until tender yet firm to the bite, about 11 minutes.

  2. Preheat the oven to 400 degrees F (200 degrees C).

  3. Meanwhile, melt butter in a large skillet over medium heat and cook mushrooms and onion until softened, about 5 minutes. Stir in flour and cook for 1 minute. Slowly whisk in milk. Add peas and corn. Simmer, stirring occasionally, until sauce thickens, about 5 minutes. Add tuna and 1/2 of the Cheddar cheese and mix to combine.

  4. Drain penne and fold into the sauce. Spread in a large baking dish.

  5. Bake in the preheated oven until cheese is melted and the top is golden, 20 to 30 minutes.

Cook's Note:

I sometimes mix a packet of crushed salted chips with the cheese to go on top (you may not need all of the bag). This adds a nice crunch to the top.
