Heat the Pot: Place a large Dutch oven or heavy-bottomed pot with a tight-fitting lid on the stove over medium heat. Drizzle some olive oil into the pan and let it warm up.
Sauté the Garlic: Add the minced garlic to the warm oil and stir continuously for about 15 seconds, just until you smell its aroma. Keep a close eye to avoid burning it.
Cook the Ground Beef: Add the ground beef into the pot and let it cook, breaking it apart with a spatula as it browns. Cook for around 10 minutes, breaking it into small pieces with a spatula or wooden spoon. Brown the beef evenly, stirring frequently to ensure it cooks thoroughly. Drain off any excess fat.
Add Liquids and Seasoning: Pour in the beef broth and marinara sauce. Add the oregano, basil, salt, and pepper to the pot and give it a good stir. Stir everything together and warm the mixture until it starts to simmer lightly.
Add Spaghetti: Break the dry spaghetti in half if needed and add it in layers, slightly overlapping. Use tongs to press the pasta down into the liquid. If some sticks out, wait a minute for it to soften, then press it down again. Make sure all the pasta is submerged.
Place the lid securely on the pot and reduce the heat to maintain a gentle simmer. Let it cook for about 20 to 25 minutes, stirring occasionally to keep the pasta from sticking. Keep an eye on the texture—the spaghetti should be tender but still have a slight bite.
Serve and Enjoy: Once the pasta is cooked to your liking, give everything a good stir and serve immediately while hot. Top with freshly grated Parmesan cheese if you like.
