Ingredients You'll Need

Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.

  • 1 lb Ground beef (80/20 blend)
  • 1 lb Spaghetti
  • 2 tbsp Olive oil
  • 1 Onion (medium, chopped)
  • 2 cloves Garlic (minced)
  • 28 oz Canned crushed tomatoes
  • 2 tbsp Tomato paste
  • 1 cup Beef broth
  • 1 tsp Cocoa powder (unsweetened)
  • 1/2 tsp Chili flakes (or more to taste)
  • to taste Salt
  • to taste Black pepper

Step-by-Step Instructions

  1. 1

    Cook the spaghetti according to package directions until al dente. Reserve about 1 cup of pasta water before draining. The starchy water will help thicken the sauce later.

    ~10 min

    Tip: Don't overcook the pasta; it will continue to cook in the sauce.
  2. 2

    While the pasta is cooking, heat the olive oil in a large skillet or pot over medium-high heat. The oil should shimmer slightly when it's hot enough, indicating it's ready for the beef.

    ~2 min

    Tip: Use a pot large enough to hold all the sauce.
  3. 3

    Add the ground beef and cook, breaking it up with a spoon, until browned. Make sure to crumble the beef well so there are no large clumps.

    ~8 min

    Tip: Drain off any excess grease to prevent a greasy sauce.
  4. 4

    Add the chopped onion and cook until softened, about 5 minutes. The onions should become translucent and fragrant, releasing their sweetness.

    ~5 min

    Tip: Stir occasionally to prevent the onions from burning.
  5. 5

    Add the minced garlic and cook for 1 minute more, until fragrant. Be careful not to burn the garlic, as it can become bitter.

    ~1 min

    Tip: Keep the heat at medium to avoid burning the garlic.
  6. 6

    Stir in the crushed tomatoes, tomato paste, beef broth, cocoa powder, and chili flakes. The cocoa powder might seem odd, but it adds a subtle richness and depth of flavor.

    ~2 min

    Tip: Use high-quality crushed tomatoes for the best flavor.
  7. 7

    Season with salt and pepper to taste. Remember that the flavors will intensify as the sauce simmers.

    ~1 min

    Tip: Start with a small amount of salt and pepper, then adjust to your preference.
  8. 8

    Bring the sauce to a simmer, then reduce the heat to low, cover, and cook for at least 20 minutes, or up to an hour, stirring occasionally. Simmering allows the flavors to meld and deepen.

    ~20 min

    Tip: The longer the sauce simmers, the richer the flavor will be.
  9. 9

    If the sauce becomes too thick, add a little of the reserved pasta water to thin it out to your desired consistency. The pasta water adds starch and helps the sauce cling to the spaghetti.

    ~2 min

    Tip: Add the pasta water a little at a time, stirring well after each addition.
  10. 10

    Add the cooked spaghetti to the sauce and toss to coat. Make sure all the spaghetti strands are well coated in the sauce.

    ~2 min

    Tip: Use tongs to toss the spaghetti and sauce together.
  11. 11

    Serve immediately, garnished with extra chili flakes or grated Parmesan cheese, if desired. The chili flakes provide an extra kick, while the Parmesan adds a salty, savory note.

    Tip: A dollop of ricotta cheese is also a delicious addition.

How Do I Know It's Ready?

The spaghetti should be al dente, and the sauce should be thick and flavorful.

Frequently Asked Questions
