Step-by-Step Recipe

- Preheat oven to 375 F if you plan to brown the top. For softer results, skip the oven step and finish on the stove.
- Cook noodles in a saucepan of boiling water until very tender – 1 to 2 minutes longer than package directions for extra softness. Drain and set aside.
- In the same saucepan, warm olive oil over medium-low heat. Add chopped onion and cook gently until soft, about 3 to 4 minutes. Do not brown.
- Add drained tuna and break into chunks with a spoon. Stir in garlic powder, lemon juice, and parsley.
- Pour in broth and milk. Stir in Greek yogurt or cream cheese until the sauce is smooth. Heat gently until just simmering so the dairy blends well. Taste and add black pepper.
- Fold in cooked noodles and peas. If the mixture seems thick, add a splash more milk to reach a creamy consistency.
- For stove-top serving: Spoon into bowls and serve warm. For a lightly crisp top: transfer to a small ovenproof dish, sprinkle breadcrumbs, and bake at 375 F for 8 to 10 minutes until bubbly. For a tiny crisp finish, broil 1 to 2 minutes but watch closely.
- Let rest 2 minutes. For easier chewing, mash slightly with a fork or press with a spoon to break up noodles and tuna into softer pieces.

FAQ
Can I use tuna in oil instead of water packed tuna?▶
Yes. Drain well and rinse to reduce extra oil. Water packed tuna is milder and lower in calories if you prefer that option.
Can I skip the oven step?▶
Absolutely. Serve right from the stove for a softer texture and fewer dishes.
Is canned tuna high in sodium?▶
Some brands are. Choose low sodium or water packed labels and follow your doctor advice about salt limits.
Can I add other vegetables?▶
Yes. Soft cooked carrots, finely chopped cooked spinach, or zucchini work well when cooked until tender.
How do I reheat without drying out the casserole?▶
Reheat gently with a splash of milk and cover while warming to keep moisture. Microwave at reduced power in short bursts, stirring between bursts.
