Ingredients

Scale
  • 8 oz dry thin spaghetti
  • 1 large white onion (thinly sliced)
  • 1 tablespoon olive oil
  • 4 tablespoons butter (divided)
  • 4 cloves garlic (pressed or minced)
  • 1–2 tablespoon chili crisp (plus more for serving)
  • 2 tablespoons soy sauce
  • 2 tablespoons honey
  • ⅔ cup half and half
  • 1 teaspoon paprika
  • ½ teaspoon garlic powder
  • ½ teaspoon Italian seasoning
  • ½ teaspoon black pepper
  • ½ cup freshly grated Parmesan
  • Fresh parsley (for garnish)

Instructions

  1. Boil the water: Start by bringing a large pot of salted water to a rolling boil.
  2. Cook the spaghetti: Once boiling, add your thin spaghetti and cook according to package instructions until al dente, about 8 to 10 minutes.
  3. Reserve pasta water: Before draining, reserve about a cup of pasta water.
  4. Heat the pan: In a large skillet, add the olive oil and 2 tablespoons of butter over medium heat.
  5. Add the onions: Toss in the thinly sliced onions and lower the heat to medium-low.
  6. Stir occasionally: Every couple of minutes, give the onions a stir for about 20-25 minutes.
  7. Enhance the flavor: Once golden-brown, add the minced garlic and stir for about a minute.
  8. Build the sauce: Pour in the soy sauce, honey, and half and half to the caramelized onions.
  9. Season it up: Sprinkle in paprika, garlic powder, Italian seasoning, and black pepper.
  10. Combine the pasta: Add the cooked pasta into the skillet with your sauce and toss to coat.
  11. Adjust consistency: If the sauce is too thick, add reserved pasta water until desired creaminess is reached.
  12. Cheese it up: Stir in the Parmesan cheese until melted and creamy.
  13. Garnish: Sprinkle fresh parsley for a pop of color and flavor.
  14. Serve and enjoy!
