One-pot spaghetti puts dinner on the table fast and with minimal cleanup. You cook the pasta right in the sauce, so the noodles soak up flavor as they cook. You end up with tender noodles and rich sauce in one pan. This recipe uses ground beef, jarred marinara, and simple seasonings. You get a complete meal in one pot, from proteins to carbs to sauce. Leftovers reheat well. And you spend more time eating and less time washing dishes.
This post will cover why one-pot spaghetti works, how to make it step by step, what you need, and ways to change it up. You’ll find a full recipe with equipment, prep times, ingredients in US and metric measures, clear instructions, and nutrition facts. Let’s get started.
Why One-Pot Spaghetti Works
One-pot meals save time in two ways. First, you cook everything together instead of in separate pots. Second, you skip draining and extra steps. Less time at the stove means dinner comes out fast.
Flavor in Every Bite
When pasta cooks in sauce, the starch it releases thickens and flavors the sauce. You don’t lose that starch down the drain. That makes the sauce silkier. Every bite has noodles coated in rich sauce.
Fewer Dishes
One pan means only one dish to wash. No colander. No extra bowls. That matters at the end of a long day. You get a hearty dinner without a sink full of pans.
Layered Nutrition
You mix protein, starch, and sauce all at once. Add vegetables, and you have a one-dish meal that covers your plate. No side dishes are needed unless you want them.
Flexible and Forgiving
You can swap ground beef for turkey or sausage. You can use different jarred sauces. You can add veggies like spinach or bell peppers. You can even make it vegetarian by skipping meat and adding beans or lentils.
What You Need
Equipment
- Large heavy-bottomed pot or deep skillet (at least 4 quarts / 4 liters)
- Wooden spoon or heat-proof spatula
- Measuring cups and spoons
- Chef’s knife and cutting board
- Ladle (optional)
A pot with a tight-fitting lid works best. The lid helps trap steam so the pasta cooks evenly. A heavy bottom keeps the sauce from scorching.
Prep Times
- Active prep: 10 minutes
- Cook time: 20 minutes
- Total time: 30 minutes
Ingredients
| Ingredient | US Measure | Metric Measure |
|---|---|---|
| Olive oil | 1 tablespoon | 15 ml |
| Lean ground beef | 1 pound | 450 g |
| Yellow onion, diced | 1 medium | 150 g |
| Garlic cloves, minced | 3 cloves | 9 g |
| Jarred marinara sauce | 24 ounces | 680 g |
| Water or broth | 2 cups | 475 ml |
| Dry spaghetti | 12 ounces | 340 g |
| Salt | 1 teaspoon | 5 g |
| Black pepper, ground | ½ teaspoon | 2.5 g |
| Dried Italian seasoning | 1 teaspoon | 2.5 g |
| Red pepper flakes (opt.) | ¼ teaspoon | 1 g |
| Fresh basil or parsley, chopped | 2 tablespoons | 8 g |
| Grated Parmesan cheese | For serving | For serving |
Notes on ingredients
- Use lean beef (at least 85% lean) so the sauce isn’t greasy.
- You can swap in ground turkey, chicken, or Italian sausage.
- If you like heat, add red pepper flakes.
- Broth adds flavor; water is okay if you have a salty sauce.
Step-by-Step Instructions
- Heat the oil. Place your pot over medium heat. Add the olive oil.
- Cook the meat. Add the ground beef. Break it up with your spoon. Cook until no pink remains, about 5–7 minutes. Season with a little salt and pepper.
- Add onion and garlic. Push the meat to one side. Add the diced onion and garlic to the empty space. Cook until the onion is soft, about 2–3 minutes. Stir to combine.
- Pour in sauce and liquid. Add the jarred marinara. Pour in the water or broth. Stir.
- Add spaghetti. Break the spaghetti in half if it doesn’t fit. Arrange the strands in the pot, pressing them into the sauce. Don’t stir yet.
- Bring to a simmer. Increase heat to medium-high just until you see bubbles. Cover and reduce heat to medium-low.
- Cook the pasta. After 5 minutes, stir gently to free noodles. Cover again. Stir every 3 minutes so the pasta cooks evenly and doesn’t stick. Total cook time is 8–10 minutes, or until al dente.
- Season. Once the noodles are tender, stir in Italian seasoning and red pepper flakes. Taste and add more salt or pepper if needed.
- Finish with herbs and cheese. Turn off the heat. Stir in fresh basil or parsley. Serve with grated Parmesan.

Tips for Success
- Use a heavy pot. Thin pans can scorch sauce.
- Don’t over-stir. Let the noodles cook undisturbed for a few minutes before stirring.
- Watch the liquid. If it evaporates too fast, add a splash more water.
- Test for doneness. Taste a strand at the end. It should be firm to the bite.
- Adjust thickness. For a thinner sauce, add more water. For thicker, remove the lid for the last few minutes.
Variations

The Science of One-Pot Pasta
When pasta cooks in sauce, starch leaches out. That starch binds with water and oil to thicken the sauce. Over time, the noodles absorb moisture and flavor. You end up with silkier sauce and noodles that taste deeper than if you drained them.
Cutting pasta into shorter lengths—or buying “pot-ready” short spaghetti—helps strands fit without breaking. Covering the pot traps steam. That steam cooks the pasta evenly from top to bottom. Stirring occasionally prevents sticking.
Ground meat browns best on medium heat without crowding the pan. Pushing it to the side lets you cook aromatics in the rendered fat. Deglazing with broth or a splash of wine unlocks browned bits that hold tons of flavor. Jarred sauce provides acidity, sweetness, and savory notes. The pasta does the rest.
Frequently Asked Questions
Can I use fresh pasta?
Yes. Fresh pasta cooks in 3–4 minutes. Reduce liquid slightly since fresh pasta releases less starch.
Why does sauce stick?
If the heat is too high or you don’t stir enough, noodles can stick and burn. Use medium to medium-low heat once simmering. Stir every few minutes.
Can I make it gluten-free?
Use gluten-free spaghetti. Cook time may vary, so follow package instructions. Check liquid levels—gluten-free pasta may need more liquid.
What if my sauce is too thin?
Remove the lid for the last few minutes to reduce extra liquid. Or stir in a small spoon of tomato paste to thicken.
Can I double the recipe?
Yes. Use a larger pot. Increase liquid to cover pasta. You may need to stir more often.
Final Thoughts
