One Pot Pasta with Tomato Sauce – Easy Stovetop Dinner Recipe
One Pot Pasta with Tomato Sauce is a simple stovetop pasta where the noodles cook right in a garlicky tomato sauce, so everything turns silky and flavorful. It’s a cozy, no-fuss dinner with minimal cleanup and big tomato-basil vibes.
Some nights you want real comfort food, but you don’t want a sink full of dishes to prove it. This is the kind of pasta you can make in one pan, stir a few times, and serve straight away.
The sauce builds fast with onion, garlic, and tomato paste, then the pasta cooks directly in that rich tomato base. The result is saucy, glossy pasta that tastes like it simmered longer than it did.

Ingredient Notes & Substitutions
Tomato sauce: Plain tomato sauce gives a smooth, classic texture. If you’re using crushed tomatoes, add an extra splash of water as needed.
Tomato paste: This deepens the flavor fast. If you skip it, the sauce will taste lighter.
Pasta shape: Short shapes work best (penne, rigatoni, ziti, rotini). If using a different shape, adjust cook time and add liquid if needed.
Water vs. stock: Stock adds extra savory flavor. Water keeps it simple and still tastes great.
Basil: Add some at the end for freshness, and save a few leaves for serving.

How to Make One Pot Pasta with Tomato Sauce
- Start the base. Heat the olive oil in a large deep skillet or pot over medium heat. Add the chopped onion and cook until softened, about 4–5 minutes.

- Build the tomato flavor. Stir in the garlic and tomato paste. Cook for about 30 seconds, just until fragrant, then add the tomato sauce and stir to combine.

- Add liquid + season. Pour in the water (or vegetable stock). Season with oregano, salt, and black pepper. Stir well and bring to a gentle simmer.

- Cook the pasta in the sauce. Add the pasta, stir, and keep it at a steady simmer. Cook until the pasta is tender and the sauce thickens, stirring occasionally so nothing sticks. If it looks too thick before the pasta is done, add a splash more water.

- Finish + serve. Turn off the heat. Stir in chopped fresh basil, then serve warm with Parmesan on top.

Expert Tips
- Use a wide, deep pan so the pasta has room to move and cook evenly.
- Stir a few times while the pasta cooks (especially in the first few minutes) to prevent sticking.
- Keep the simmer gentle; a hard boil can reduce the liquid too fast.
- If your pasta needs more time, add water in small splashes (2–4 tbsp at a time).
- Taste near the end and adjust salt—tomato sauces can vary a lot.
- Let it sit 2 minutes off the heat before serving; the sauce thickens slightly and clings better.
- For a deeper flavor, cook the tomato paste for a full minute before adding the sauce.
Storage & Freezing
- Fridge: Store leftovers in an airtight container for up to 4 days.
- Reheat: Warm on the stove or in the microwave with a splash of water to loosen the sauce.
- Freezer: Pasta can be frozen for up to 2 months, but the texture is best fresh. If you plan to freeze, slightly undercook the pasta and thaw overnight in the fridge before reheating.
- Thawing: Thaw in the fridge overnight, then reheat with a little water and stir until creamy again.
Variations
- Spicy tomato pasta: Add red pepper flakes while simmering.
- Veggie boost: Stir in spinach at the end or add diced bell peppers with the onion.
- Creamy tomato: Add 2–3 tbsp heavy cream at the end for a rosé-style sauce.
- Protein add-on: Add cooked chicken, shrimp, or chickpeas near the end to warm through.
- Cheesy finish: Stir in a handful of shredded mozzarella right before serving.
