This 3-ingredient oven retro tubetti casserole is the kind of simple comfort my mother leaned on whenever company was coming and the house was already buzzing with a dozen other things. She called it her “company casserole” because it could slide into the oven while she set the table and fixed a salad, and it always came out with that bubbling, golden cheese blanket that made everyone feel cared for. It’s pure Midwestern practicality: pantry pasta, a good jar of tomato sauce, and plenty of cheese baked until the edges are just a little bit charred. I learned this one at her elbow, and now I make it every Mother’s Day and any time I want the house to smell like my childhood kitchen.
Serve this rich, cheesy tubetti casserole with a crisp green salad dressed in a simple vinaigrette to cut through the creaminess, and add some warm garlic bread or buttered dinner rolls for soaking up the extra sauce. A dish of green beans or steamed broccoli on the side keeps it feeling like a proper Sunday supper. For company, I like to put a bowl of grated Parmesan on the table and a little jar of red pepper flakes so folks can dress up their own plates as they like, along with a pitcher of iced tea or a light red wine.
3-Ingredient Retro Tubetti CasseroleServings: 6
Ingredients
12 oz (about 3 1/2 cups) dry tubetti pasta
3 cups (24 oz) jarred tomato pasta sauce, your favorite mild or marinara style
4 cups (about 16 oz) shredded low-moisture mozzarella cheese, divided
Directions
Preheat your oven to 375°F (190°C). Lightly butter or oil a medium oval or 9x13-inch ceramic baking dish so the pasta and cheese release easily and the edges can crisp nicely.
Bring a large pot of well-salted water to a boil. Add the tubetti pasta and cook just until very al dente, about 2 minutes less than the package directions. The pasta will finish softening in the oven, and starting a bit firm keeps it from turning mushy.
Drain the tubetti well and return it to the warm pot. Immediately pour in the jarred tomato pasta sauce and add 2 cups of the shredded mozzarella. Stir until every little tube of pasta is coated and the cheese is evenly tucked throughout.
Spoon the saucy tubetti mixture into the prepared baking dish, spreading it into an even layer so there are no dry pockets. Gently press it down with the back of a spoon so the top is fairly level; this helps the cheese blanket melt and brown evenly.
Sprinkle the remaining 2 cups of shredded mozzarella over the top, covering the pasta completely from edge to edge. A few little hills and valleys in the cheese are fine; they’ll turn into those lovely caramelized, bubbly spots.
Place the baking dish on the middle oven rack and bake uncovered for 25–30 minutes, until the cheese is melted, bubbling around the edges, and starting to turn a deep golden brown. For a more old-fashioned, slightly charred top, move the dish to the upper rack for the last 3–5 minutes, watching closely so it doesn’t burn.
When the top is deeply golden with some darker, crisp spots and you can see little bubbles of sauce peeking up around the sides, remove the casserole from the oven. Let it rest on a heatproof surface for at least 10 minutes so the cheese sets a bit and the pasta layers hold together.
Carry the dish straight to the table, just the way my mother did, and serve the tubetti casserole warm, scooping down through the molten cheese blanket so each portion gets plenty of pasta, sauce, and those treasured caramelized edges.
Variations & Tips
You can keep the spirit of this three-ingredient casserole while nudging it in different directions. For a slightly richer flavor, use a jarred tomato-basil or roasted garlic pasta sauce; if your sauce is very thick, you may want to add a splash of water before mixing it with the pasta so it doesn’t dry out in the oven. If you prefer a saltier, sharper top, swap 1 cup of the mozzarella for shredded provolone or a mild white cheddar, still keeping the total cheese amount the same. To stretch the recipe for a bigger crowd without complicating it, cook up to 16 oz of tubetti and increase both the sauce and cheese proportionally so everything stays saucy and well covered. For a softer, less browned top, cover the dish loosely with foil for the first 20 minutes of baking, then uncover just long enough to get a light golden color. Leftovers should be cooled, then refrigerated within 2 hours in a covered container and eaten within 3–4 days; reheat thoroughly until the center is steaming hot. Because this casserole is dense and cheesy, make sure it is heated all the way through when reheating—cover with foil and warm in a 325°F (165°C) oven until hot in the middle, then uncover briefly to re-crisp the top if you like. Always use pasteurized cheese and a reputable, unopened jar of sauce, and discard any sauce that looks or smells off before using. If you prepare the dish ahead, keep it refrigerated and bake within 24 hours, adding a few extra minutes of baking time if it goes into the oven cold.
