This oven baked 4-ingredient macaroni and tomato bake is straight out of my Midwestern childhood. My grandma used to make it on busy weeknights when everyone was coming and going from work, school, and sports, and somehow this simple little dish made the whole house feel cozy. It still blows my mind that something this comforting comes from just four pantry staples—no fancy sauces, no extra steps. Everything bakes together in one glass dish, the pasta soaking up the tomatoey juices while a blanket of sharp cheddar melts and bubbles on top. It’s the kind of recipe you reach for when you’re tired, hungry, and just want something warm and nostalgic in the oven with almost no effort.
Serve this macaroni and tomato bake straight from the glass baking dish with a big spoon—it's very much a scoop-and-serve situation. I like it with a simple green salad or steamed broccoli to balance the richness, but garlic bread or buttered toast is great if you’re leaning into full comfort mode. A little black pepper or crushed red pepper on top at the table is nice if you like a bit of heat, and if you’re feeding a crowd, this pairs easily with baked chicken, meatloaf, or even just some sliced smoked sausage on the side.
Oven Baked 4-Ingredient Macaroni and Tomato BakeServings: 4
Ingredients
2 cups dry elbow macaroni (about 8 oz)
1 can (28 oz) crushed or diced tomatoes, undrained
2 cups shredded sharp cheddar cheese, divided
2 cups water
1 teaspoon salt (optional, to taste)
1/2 teaspoon black pepper (optional, to taste)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 2 to 2 1/2-quart glass baking dish (an 8x11-inch or 9x13-inch works) with a bit of oil or nonstick spray.
Pour the dry elbow macaroni into the glass baking dish, spreading it into an even layer so it cooks evenly.
In a large bowl or measuring pitcher, combine the can of crushed or diced tomatoes (with all their juices), the water, salt, and black pepper. Stir to mix well.
Pour the tomato mixture evenly over the dry macaroni in the baking dish. Gently stir in the dish just enough so the pasta is mostly submerged and distributed, but don’t worry if a few pieces are peeking out.
Sprinkle 1 cup of the shredded sharp cheddar cheese evenly over the top. Reserve the remaining 1 cup for later.
Cover the baking dish tightly with foil, making sure to crimp the edges so steam doesn’t escape. This helps the pasta cook through without drying out.
Bake covered for 35 to 40 minutes, until the pasta is mostly tender when you test a piece from the center with a fork. If it still feels very firm, recover and bake for another 5 to 10 minutes.
Carefully remove the foil (watch for steam), then sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top of the macaroni and tomato mixture.
Return the dish to the oven, uncovered, and bake for another 10 to 15 minutes, or until the cheese is fully melted, bubbly, and lightly golden around the edges.
Let the macaroni and tomato bake rest for about 5 to 10 minutes before serving. This helps it set up a bit and makes it easier to scoop clean servings from the glass dish. Serve warm, straight from the pan.
Variations & Tips
To keep the spirit of the original 4-ingredient comfort dish, I like to think of variations as small tweaks rather than full-on makeovers. If you want more flavor without changing the core ingredients, try using fire-roasted canned tomatoes instead of regular, or a can with basil and garlic already added. For a slightly creamier version, swap 1/2 cup of the water for milk, stirring it into the tomato mixture before baking. You can also play with different cheeses: half cheddar and half mozzarella melts beautifully, while a little pepper jack mixed into the top layer adds a gentle kick. If you’re cooking ahead, assemble the dish up through adding the first layer of cheese, cover, and refrigerate for up to 24 hours; you may need to add 5 to 10 extra minutes to the covered bake time since it will be starting cold. Leftovers reheat well in the microwave with a splash of water to loosen the pasta, or in a small baking dish covered with foil at 325°F until warmed through. For anyone who wants a bit of crunch, you can sprinkle a handful of crushed crackers or plain breadcrumbs over the top cheese layer before the final bake, though my grandma always kept it classic with just that melted cheddar blanket.
