Most pasta bake recipes online have 12 ingredients including things like fresh basil and ricotta, which means the cost per dinner is closer to $20 and the prep takes an hour. The 5-ingredient version uses pantry staples that are probably already in your kitchen, costs about $11 for 6 servings, and goes from box to table in 35 minutes.
A 5-ingredient pasta bake is what real weeknight cooking looks like for families on a budget. Here is the method.
The Five Ingredients
One pound of penne or rotini pasta. One pound of ground beef (80/20 works best, since leaner cuts come out dry). One 24-ounce jar of marinara sauce (any brand on sale: Rao’s is the gold standard if it is not too expensive at your store, but a $3 jar of Classico produces a good bake). 8 ounces of shredded mozzarella. Half a cup of shredded Parmesan. Salt and pepper from your existing pantry do not count as additional ingredients.
The whole grocery list runs $10 to $13 depending on local prices and what is on sale. For a family of 4, this leaves enough for 2 lunch portions the next day, which makes it one of the best cost-per-serving dinners that does not feel like a budget meal.
The Method
Heat the oven to 425 degrees. Bring a large pot of salted water to a boil. While the water heats, brown the ground beef in a large skillet over medium-high heat. Break it up into small pieces with a wooden spoon, season with half a teaspoon of salt and quarter teaspoon of black pepper. Cook until no pink remains, about 8 minutes. Drain off any excess grease.
Add the pasta to the boiling water and cook 2 minutes less than the package time for al dente. The pasta will continue cooking in the oven, so undercooking the boil prevents mushy pasta in the final bake. Drain and return to the pot.
Add the cooked beef and the entire jar of marinara to the pasta in the pot. Stir until everything is coated. Transfer half the mixture to a 9×13 baking dish. Sprinkle half the mozzarella over this layer. Add the remaining pasta, then top with the remaining mozzarella and the Parmesan.
Bake uncovered for 20 minutes until the cheese is melted, golden brown in spots, and the edges are bubbling. The 425-degree heat is what produces the brown crust that distinguishes a pasta bake from just pasta with cheese on top. Lower temperatures produce pale, soft cheese that does not have the same texture appeal.
Make-Ahead and Freezer Notes
The bake can be assembled completely up to 24 hours in advance, covered, and refrigerated. When ready to cook, add 10 minutes to the bake time to account for the cold start. For freezing, assemble in a foil pan, cover with foil, and freeze for up to 3 months. Bake from frozen at 375 degrees for 60 minutes, then remove the foil and finish at 425 for 15 minutes to brown the top.
Doubling the recipe is straightforward. Make two pans, bake one tonight and freeze the other. The marginal time cost of the second pan is 5 minutes (more pasta to drain and assemble) but you have saved a full dinner for a future busy night.
Variations Without Adding Ingredients
Italian sausage instead of ground beef adds significant flavor without adding cost when sausage is on sale. A teaspoon of red pepper flakes added with the salt and pepper produces a slight kick the kids will not notice but the adults will appreciate. Substituting half the mozzarella for cheddar produces a different flavor profile that some families prefer.
For a vegetarian version, swap the ground beef for a cup of frozen spinach (thawed and squeezed dry) plus a can of drained white beans. The protein and bulk are still there but the cost drops to about $7 per pan.
