Ingredients

Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large pot over medium-high heat, add 12 oz lean ground beef, and cook, breaking it into small crumbles, until browned and no longer pink (6-7 minutes).
  2. Step 2: Reduce heat to medium, add 1 medium finely diced onion, 1/2 cup finely diced carrot, and 1/2 cup finely diced celery; cook for 5 minutes until vegetables are softened and translucent.
  3. Step 3: Stir in 8 oz finely chopped cremini mushrooms, 1 tsp dried oregano, and 1/2 cup red wine, then simmer for 3 minutes until the wine evaporates and the mushrooms release their liquid.
  4. Step 4: Add 1 cup tomato passata, reduce heat to low, and simmer covered for 45 minutes, stirring occasionally until the sauce thickens and coats the back of a spoon.
  5. Step 5: Cook 12 oz spaghetti according to package directions until al dente, then toss with 2 tbsp chopped fresh basil and serve the bolognese sauce over the pasta.
