This oven baked 4-ingredient navy bean pasta is the kind of simple, filling supper my mother would have leaned on during the lean years—what folks now like to call a Depression-era style meal. Everything goes right into one deep glass casserole dish: dry ditalini pasta on the bottom, canned navy beans poured and stirred over the top, then just enough tomato sauce and water to pull it all together. It bakes up into a humble, hearty dish that somehow disappears faster than anything else I make, especially on busy weeknights when no one wants to fuss but everyone wants to eat well.
Serve this navy bean pasta straight from the casserole dish, with a big spoon for scooping. A simple green salad with a sharp vinaigrette helps cut through the richness, and a slice of buttered white bread or cornbread is perfect for mopping up the tomatoey bean sauce. If you like, offer a bowl of grated Parmesan or cheddar at the table so folks can sprinkle their own. A jar of pickled beets or dill pickles on the side gives it that old-fashioned Midwestern touch I grew up with.
Oven-Baked 4-Ingredient Navy Bean Ditalini CasseroleServings: 4
Ingredients
2 cups uncooked ditalini pasta
2 cans (15 ounces each) navy beans, drained and rinsed
2 cups canned tomato sauce (plain, unseasoned if possible)
2 cups water
1 teaspoon salt (or to taste, optional)
1/2 teaspoon black pepper (optional)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a deep 2 1/2- to 3-quart glass casserole dish so the pasta doesn’t stick.
Pour the uncooked ditalini pasta evenly into the bottom of the casserole dish, spreading it out so it forms a fairly even layer.
Add the drained and rinsed canned navy beans right over the dry pasta, scattering them across the top. With clean hands or a large spoon, gently stir the beans into the pasta so they’re well mixed together in the dish. This is the moment that looks just like the old kitchen snapshots: hands stirring beans over dry pasta in a glass casserole.
In a bowl or large measuring cup, whisk together the canned tomato sauce, water, salt, and black pepper (if using) until well combined. The mixture will look thin, but the pasta will soak it up as it bakes.
Pour the tomato sauce mixture evenly over the bean and pasta mixture in the casserole dish, making sure all the pasta is moistened. If any pasta is sticking up dry, press it down gently with the back of a spoon so it’s submerged.
Cover the casserole dish tightly with foil to trap the steam, which helps the ditalini cook through without boiling it first.
Bake in the preheated oven for 35 to 40 minutes. Carefully remove the foil (watch for steam), then stir the casserole well, scraping along the bottom to loosen any pasta that might be settling.
Return the uncovered casserole to the oven and bake for another 10 to 15 minutes, or until the pasta is tender and most of the liquid has been absorbed into a thick, saucy mixture. If it looks too dry before the pasta is done, stir in a splash more hot water and keep baking a few more minutes.
Let the casserole rest for 5 to 10 minutes after removing it from the oven. This short rest allows the sauce to thicken and the flavors to settle, just like the hearty bakes my mother used to make. Spoon into bowls and serve warm.
Variations & Tips
To keep the spirit of a 4-ingredient, Depression-era style meal, think of extras as optional, not required. For a cheesier version, sprinkle 1 cup of shredded cheddar or mozzarella over the top during the last 10 minutes of baking. If you have an onion on hand, finely chop it and stir it in with the beans and pasta for a little extra sweetness and depth. A teaspoon of dried Italian seasoning or a pinch of dried basil and oregano stirred into the tomato sauce mixture gives it a more modern, herby flavor. For a bit more protein, you can add 1 cup of cooked crumbled sausage or ground beef to the bean and pasta mixture—this stretches the dish even further, the way farm families often did to feed a crowd. If you prefer a looser, more soupy casserole (like the ones that sat on low all afternoon at church suppers), simply add an extra 1/2 to 1 cup of water before baking and check the pasta a few minutes early. Leftovers reheat nicely with a splash of water and can be turned into a new meal by topping with a fried egg or serving alongside cooked greens.
