There is something mighty comforting about a pantry supper that asks so little of you and still comes out hot, filling, and satisfying. This 4-Ingredient Oven Baked Tuna Rotini is the kind of practical meal folks across the Midwest have leaned on for generations, using canned fish, dry pasta, and a creamy pantry staple to make dinner stretch without fuss. It is the sort of simple bake that belongs on a busy weeknight table, especially when you want a hearty dish with hardly any chopping and almost no mess.
Serve this tuna rotini with a simple green salad, buttery green beans, or sweet peas for a little color on the plate. A slice of toasted garlic bread or plain buttered bread goes especially well for scooping up the creamy sauce, and if you like a little brightness, a wedge of lemon on the side helps cut the richness nicely.
4-Ingredient Oven Baked Tuna Rotini
Servings: 4 to 6
Ingredients
12 ounces dry uncooked rotini pasta
2 cans (5 ounces each) tuna, undrained
1 can (10 1/2 ounces) condensed cream of mushroom soup
2 1/2 cups water
Directions
1. Preheat the oven to 400°F and lightly grease a 9x13-inch oven-safe baking dish.
2. Pour the dry uncooked rotini into the baking dish, then spoon the undrained tuna over the top.
3. Add the condensed cream of mushroom soup and water, then stir everything together well so the pasta is evenly coated and mostly submerged.
4. Cover the dish tightly with foil and bake for 35 minutes.
5. Remove the foil, stir the pasta well, then return the dish to the oven uncovered for 10 to 15 minutes more, or until the rotini is tender and most of the liquid is absorbed.
6. Let the casserole rest for 5 minutes before serving so the sauce can settle and cling to the pasta.
Variations & Tips
Add a little cheese: If you do not mind stretching past four ingredients, a small handful of shredded cheddar or mozzarella sprinkled on during the last 10 minutes of baking gives the top a nice golden finish and a little extra richness.
Make it creamier: If the pasta looks a touch dry before it finishes baking, stir in an extra splash of hot water, cover again, and bake a few minutes longer. Different brands of pasta can soak up liquid a little differently.
Try a different soup: Cream of celery or cream of chicken can be used in place of cream of mushroom if that is what you have in the pantry. Each one gives the casserole its own familiar, old-fashioned flavor.
Season to taste: Even simple casseroles benefit from a little black pepper, dried parsley, or onion powder. Since canned tuna and soup already bring salt, it is best to taste first before adding any extra.
Use a smaller pasta if needed: If rotini is not on the shelf, small shells or elbows work well too. Just keep an eye on the liquid and tenderness, since smaller shapes sometimes bake up a bit faster.
