One Pot Spaghetti is the ultimate fuss-free dinner! Tender pasta and a hearty, flavorful meat sauce come together in just one pot—less cleanup, more flavor.
Heat oil in a large pot over medium-high heat. Add mirepoix, cooking for 6–8 minutes or until veggies are soft. Push veggies to edges of the pan.
Add beef in center of pan. Allow it to sear for about 1 min per side, then break it apart with a wooden spoon as it cooks. Continue until the beef is mostly browned, with some pink remaining.
Mix in the garlic, Italian seasoning, beef bouillon (start with 1 tsp), and tomato paste. Season with pepper; I add 3/4 tsp. Stir and continue to cook until beef is fully browned through.
Add marinara, tomato sauce, chicken broth, and (optional) Worcestershire. Stir and allow to come to a boil.
Break spaghetti in half and submerge it in the liquid. Cook for 10–12 minutes, stirring often and scraping the bottom of the pot to prevent pasta sticking. About 8–10 minutes in, reduce heat to medium to avoid evaporating too much liquid before pasta is done (see note 4 for troubleshooting).
Once pasta is al dente (slightly firmer than you want), remove the pot from heat. The dish should still be quite saucy. Using tongs, toss the pasta for about a minute until the sauce thickens and pasta is perfectly tender. Taste and adjust seasoning; adding extra 1 tsp bouillon if you feel it needs it.
Use tongs to dish up plates, grating Parmesan cheese with a fine grater directly on top. Sprinkle parsley or basil on plates if desired. Enjoy immediately.
Notes

Use a food scale (if possible) to be precise here!Note 3: Serving suggestions:salt and pepper, parmesan cheese, parsley, or basil.
Note 4: Troubleshooting:
