Cookware
can opener · chef's knife · colander · cutting board · grater · measuring cups · measuring spoons · medium saucepan · oven mitts · stainless steel sauté pan · stirring spoon
Directions
- Boil a pot of salted water, then add the penne and cook until al dente, about 8–10 minutes; drain and set aside.
- Heat a sauté pan over medium heat and melt a bit of butter, then add the onion and sliced mushrooms; cook until softened, 3–4 minutes.
- Sprinkle flour over the onions and mushrooms, stir to coat evenly, and cook for 1 minute to remove raw flour taste.
- Pour in the milk gradually, stirring constantly, and simmer until the sauce thickens slightly, about 5 minutes.
- Stir in the tuna, peas, grated Parmesan, paprika, salt, and pepper until everything is evenly coated; remove from heat.
- Fold the cooked pasta into the sauce until fully coated, then transfer to a broiler-safe dish.
- Broil briefly until the top is lightly golden, about 3–4 minutes, then serve warm.
Two tips
- Make-ahead: cook the pasta and store it, tightly covered, for up to 1 day.
- Serving idea: top leftovers with a light grating of Parmesan and a pinch of paprika for extra color and flavor.
