  • Total Time: 1 hour 15 minutes
  • Yield: 6 servings

Ingredients

Scale
  • 3 tbsp olive oil
  • 2 tbsp unsalted butter
  • 3 large yellow onions, sliced 1/8-inch thick
  • 1/8 tsp salt
  • 1/8 tsp pepper
  • 4 garlic cloves, minced
  • pinch–1/4 tsp red pepper flakes
  • 1 tbsp Worcestershire sauce
  • 1 tbsp reduced sodium soy sauce
  • 5 1/2 cups water (or beef broth)
  • 1 12 oz can evaporated milk
  • 1/2 tbsp cornstarch
  • 2 tbsp beef bouillon (optional if using broth)
  • 1 tbsp fresh parsley, minced (or 1 tsp dried)
  • 2 tsp fresh thyme, minced (or 3/4 tsp dried)
  • 1/2 tsp dried oregano
  • 1/2 tsp paprika
  • 1/2 tsp pepper
  • 1 lb short cut pasta (e.g., orecchiette)
  • 5 oz freshly shredded Gruyere cheese
  • 1/4 cup freshly shredded Parmesan cheese
  • Fresh parsley for garnish (optional)

Instructions

  1. Caramelize Onions: Melt butter in olive oil in a large Dutch oven over medium heat. Add onions, salt, and pepper. Cook, stirring occasionally, until dark golden brown, 30-35 minutes. Add more butter/olive oil if onions start to scorch.
  2. Make Sauce: Add garlic, red pepper flakes, soy sauce, and Worcestershire sauce. Cook 30 seconds. Add water and half of evaporated milk. Whisk remaining evaporated milk with cornstarch and stir in. Bring to boil, then add beef bouillon, parsley, thyme, oregano, paprika, and pepper.
  3. Cook Pasta: Add pasta to boiling mixture. Reduce to medium-high heat, simmer uncovered for 20–25 minutes, stirring often until pasta is al dente and coated in liquid. Add extra water if necessary.
  4. Add Cheeses: Remove pan from heat. Stir in Gruyere cheese a handful at a time until melted, then add Parmesan until melted. Adjust seasoning with salt and pepper. For saucier pasta, add extra water or milk. Garnish with fresh parsley if desired.

Notes

  • Meal Prep: Slice onions ahead and store in fridge up to 2 days. Caramelize and add sauce (minus pasta and cheese) for quicker cooking later.
  • Leftovers: Store cooled pasta in airtight container in fridge up to 5 days. Reheat with splash of water or milk if desired.
