Ingredients
Main Ingredients
- 12 oz (340 g) spaghetti
- 1 medium onion, thinly sliced
- 4 garlic cloves, minced
- 1 cup cherry tomatoes, halved
- 1 small bell pepper, sliced
- 3 cups vegetable broth or chicken broth
- 2 cups tomato sauce
- 2 tablespoons olive oil
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon paprika
- Salt and black pepper to taste
- Fresh basil or parsley for garnish
Optional Add-Ins

How to Make the Easiest One-Pot Spaghetti
1. Sauté the onion and garlic
Heat olive oil in a large pot over medium heat. Add onion and garlic, and cook for 2 to 3 minutes until soft and fragrant.
2. Add spaghetti and liquids
Place the dry spaghetti directly into the pot. Pour in the vegetable broth and tomato sauce. Gently press the pasta so it sits under the liquid.
3. Add the vegetables
Stir in cherry tomatoes and sliced bell pepper. They will soften and release flavor as they cook.
4. Season the pot
Add oregano, basil, paprika, salt, and pepper. Stir lightly to distribute the seasonings evenly.
5. Simmer until tender
Bring the pot to a light boil. Reduce heat and simmer uncovered for 12 to 14 minutes. Stir occasionally to prevent sticking and help the sauce thicken.
6. Serve with fresh herbs
Once the spaghetti is tender and the sauce has thickened to a glossy, creamy consistency, remove from heat. Top with fresh basil or parsley before serving.
Why the One-Pot Method Works
Cooking pasta in the sauce instead of boiling it separately unlocks deeper flavor. As the spaghetti cooks, it releases natural starches that thicken the sauce, eliminating the need for cream or added thickeners. The result is a velvety, rich spaghetti dish made with minimal effort.
