Brown the Beef for Maximum Flavor
Heat a drizzle of olive oil in a large pot over medium-high. Add the ground beef in chunks and let it brown, do not rush it. Let it get crispy and golden for that deep beefy flavor. Break it up into fine bits as it cooks. Season generously with salt and pepper. Once browned and cooked through, transfer the beef to a bowl but do not clean the pot. The brown bits (called fond) stuck to the bottom are flavored gold.
Sauté the Aromatics
In the same pot, add your diced onion, carrot, celery, and garlic. This aromatic base (mirepoix or soffritto, depending on who you ask) adds depth to the sauce. Sauté for 5-6 minutes until softened and slightly golden.
Add Tomato Paste
Stir in the tomato paste and let it caramelize for 1-2 minutes. This step is key it deepens the flavor and brings out a natural sweetness.
Build the Sauce
Pour in the beef broth and water. Stir to loosen all those flavorful bits on the bottom. Bring to a simmer. Now, carefully blend the sauce using an immersion blender or transfer it to a standard blender. This gives the sauce that silky texture you remember from the canned version - but with actual body and flavor.
Cook the Pasta Right in the Sauce
Once the sauce is smooth and bubbling, stir in your dry pasta and return the cooked beef to the pot. Season again with salt and pepper. Let it simmer uncovered, stirring occasionally, for about 12 minutes, or until the pasta is tender and the sauce thickens. As the pasta cooks, it releases starch into the sauce, naturally thickening it into that creamy, clingy texture we all know and love.
Add the Cheese and Serve
Once the pasta is cooked and the sauce is thick, turn off the heat. Stir in your grated Romano cheese until melty and luscious. That is, it!
