- 1 teaspoon Italian seasoning: A blend of herbs that ties the dish together with a classic Italian vibe.
- ¼ teaspoon red pepper flakes (optional): For just a hint of spicy warmth.
- 1 (24 oz) jar marinara sauce: The rich tomato base that coats every strand of spaghetti.
- 3 cups water or beef broth: Required to cook the pasta while infusing extra flavor depending on your choice.

How to Make Easy One Pot Spaghetti Recipe
Step 1: Sauté Aromatics
Begin by heating the olive oil in a large deep skillet or Dutch oven over medium heat. Toss in the finely chopped onion and sauté it for about 3 to 4 minutes until it becomes soft and translucent. Then add the minced garlic and cook for just 30 seconds more until fragrant. This creates the flavorful foundation your spaghetti will build on.
Step 2: Brown the Meat
Next, add your ground beef or Italian sausage into the skillet. Break it apart with a spatula and cook for 6 to 8 minutes until fully browned and crumbly. Make sure to drain any excess fat so your dish doesn’t turn greasy, but the rich meaty flavor stays perfectly intact.
Step 3: Season to Perfection
Sprinkle in the salt, black pepper, Italian seasoning, and, if you like a bit of heat, red pepper flakes. Stir everything together, letting those herbs and spices marry with the meat and onions for that classic pasta taste.
Step 4: Combine Pasta and Sauce
Now for the fun part—add the dry spaghetti straight to the pot. If your pan is not quite wide enough, break the spaghetti in half. Pour in the jar of marinara sauce and the 3 cups of water or broth. Stir gently to combine all the components without breaking the pasta noodles.
Step 5: Simmer Until Tender
Bring the mixture to a boil, then reduce the heat to medium-low. Cover the pot and let it simmer for 12 to 15 minutes. Stir occasionally to prevent sticking and to check that the spaghetti is soft and has absorbed most of the flavorful liquid. This one pot method means the pasta soaks up all those incredible flavors right inside the skillet.
Step 6: Finish with Cheese
Once the spaghetti is perfectly tender, remove the pot from heat. Stir in the grated Parmesan cheese which melts in beautifully, adding a creamy and tangy note. Let the dish rest for a couple of minutes so the sauce thickens slightly and flavors meld even more.
How to Serve Easy One Pot Spaghetti Recipe

Garnishes
A sprinkle of fresh chopped parsley or basil instantly brightens this dish visually and adds a lovely herbal freshness. For extra indulgence, don’t be shy about adding a little more Parmesan on top just before serving.
Side Dishes
This one pot spaghetti pairs wonderfully with a crisp green salad dressed in a tangy vinaigrette or some garlicky roasted vegetables for a balanced meal. Crunchy garlic bread on the side is another fantastic choice to soak up every bit of the sauce.
Creative Ways to Present
Serve the pasta in deep bowls to hold all the juicy sauce, then garnish each plate with a small pile of grated Parmesan and a fresh herb sprig for an elegant touch. For a fun twist, serve with a side of sautéed mushrooms stirred into the pasta just before plating or mix in baby spinach while the pasta simmers for added color and nutrition.
Make Ahead and Storage
Storing Leftovers
Place any leftover spaghetti in an airtight container and store it in the refrigerator. It will stay delicious for up to 3 days, making it perfect for quick lunches or easy dinners later in the week.
Freezing
This Easy One Pot Spaghetti Recipe freezes well too. You can portion out the cooked pasta into freezer-safe containers or bags and freeze for up to 2 months. Just be sure to cool it completely before sealing to maintain the best texture.
Reheating
When you’re ready to enjoy leftovers, reheat gently on the stove over low heat or in the microwave with a splash of water to loosen the sauce. Stir occasionally to evenly warm and keep the spaghetti from drying out.
FAQs
Can I use whole wheat or gluten-free spaghetti for this recipe?
Absolutely! Feel free to swap in your preferred pasta type, but keep an eye on cooking times as whole wheat and gluten-free noodles can vary in how quickly they cook.
Is it possible to make this recipe vegetarian?
Yes, you can substitute the ground meat for plant-based alternatives or simply omit it entirely and add extra vegetables like mushrooms or spinach for a satisfying vegetarian meal.
Can I use fresh tomatoes instead of marinara sauce?
While fresh tomatoes could work, the marinara sauce provides a consistent, flavorful base that enriches the dish. If you use fresh tomatoes, you may want to cook them down into a sauce first for best results.
What if I don’t have Italian seasoning?
No worries! You can mix your own with dried basil, oregano, thyme, and rosemary or simply add each herb individually to taste.
How spicy is the recipe with red pepper flakes?
The red pepper flakes add just a touch of warmth without overpowering the dish, but you can adjust the amount or leave it out completely based on your heat preference.
