Easy Tuna Casserole Without Canned Soup
This creamy from-scratch tuna noodle casserole makes a small, gentle meal for one or two. It uses a simple white sauce instead of canned soup so you can control sodium and texture.
Cooking just for yourself or for two is easier when recipes are small, forgiving, and use regular pantry items. This casserole is made in one pan and a small baking dish so you do not have a lot to wash afterward.
The white sauce is light and smooth, and you can make the pasta extra soft if you prefer. It is a comforting dinner or a filling lunch that is easy on the stomach.
Ingredients You’ll Need
- 4 ounces small pasta such as small shells or elbows (about 1 cup dry)
- 1 tablespoon unsalted butter
- 1 tablespoon all-purpose flour
- 1 cup low-fat milk or lactose-free milk
- 1/4 cup low-sodium chicken or vegetable broth
- 1 5-ounce can tuna in water, drained and flaked
- 1/3 cup frozen peas or finely diced soft-cooked carrots
- 1/3 cup shredded mild cheddar or Monterey jack
- 1 teaspoon lemon juice
- Salt and black pepper to taste – use sparingly
- Optional: 1 tablespoon plain panko or breadcrumbs for a light topping
You can serve this creamy tuna casserole with a small side of rice, mashed potatoes, or soft bread if you like.
Step-by-Step Recipe
- Start to finish about 35 minutes.
- Preheat the oven to 350 F and lightly grease a small ovenproof dish (about 1 to 1.5 quart) or use an ovenproof skillet.
- Bring a pot of lightly salted water to a boil and cook the pasta 1 to 2 minutes longer than package directions for a softer texture. Drain and set aside.
- In a small saucepan over medium heat, melt the butter. Sprinkle in the flour and stir for 30 seconds to form a paste.
- Slowly whisk in the milk and broth until smooth. Cook and stir until the sauce thickens and coats the back of a spoon, about 3 to 5 minutes. Reduce heat if it bubbles too fast.
- Stir in the cheese until melted, then add lemon juice, peas or carrots, and flaked tuna. Taste and add a pinch of salt and pepper if you need it.
- Fold the cooked pasta into the sauce. Spoon into the prepared dish. Sprinkle panko on top if using.
- Bake for 12 to 15 minutes until warmed through and lightly golden. Let rest for 3 minutes before serving to keep the texture soft.
Tips and Easy Variations
Make it easier to chew
- Use small pasta shapes or break pasta pieces before cooking for gentler bites
- Cook the pasta a bit longer than package directions for a very soft texture
- Choose soft cooked vegetables like diced carrots or thawed peas for easy chewing
Reduce salt and fat
- Use low-sodium broth and rinse canned tuna under cold water to cut sodium
- Swap whole milk for low-fat or lactose-free milk and use less butter for the roux
- If you must limit salt, skip added salt and boost flavor with lemon and herbs
Swaps and no oven method
- Vegetarian option – use cooked white beans instead of tuna for soft protein
- No oven needed – skip baking and serve directly from the saucepan for fewer dishes
- For lighter digestion, avoid heavy toppings and keep cheese to a moderate amount
Quick care notes
- Overcook the pasta by a minute or two for very soft texture
- Reheat with a splash of milk to restore a smooth white sauce
- Do not freeze if you want the best sauce texture
Storage and Leftovers
Fridge
Cool leftovers to room temperature, cover, and refrigerate up to 2 days.

Freezing is not recommended because the white sauce can separate when thawed.
Reheating
Reheat gently in a small saucepan or microwave with a splash of milk to keep the sauce smooth and soft.
