This meat sauce has slow-cooked flavor (without requiring hours at the stove). Use it in our Famous Lasagna or atop some spaghetti for dinner tonight.
Heat oil in a large skillet over medium-high heat. Add onion, garlic, salt, and pepper. Cook until softened, 3 to 5 minutes.
Add beef and cook, breaking up with a spoon until no longer pink, 4 to 5 minutes. Add tomato paste and cook 1 to 2 minutes.
Add tomatoes and juice, breaking up tomatoes. Simmer over medium heat until thickened and saucy, 45 to 60 minutes. Season with salt and pepper, to taste.
