Servings
Ingredients
- 1 onion
- 4 cloves garlic
- 2 tbsp chili crisp
- 1 cup cream
- 1 cup coconut milk
- 1 tbsp soy sauce
- 1/2 cup Parmesan cheese
- 8 oz pasta
- 2 tbsp butter
- 1 tbsp olive oil
- 1 tsp paprika
- 1 tsp garlic powder
- 1 tsp salt
- 1 tsp pepper
- 1 tsp Italian seasoning
Instructions
- 1Slice the onion thinly and mince the garlic; measure out all seasonings and bring the cream or coconut milk to room temperature.
- 2Heat 2 tbsp butter and 1 tbsp olive oil in a large skillet over medium heat. Add the onions and cook, stirring occasionally, for 15–20 minutes until golden and jammy, adding a splash of water if they begin to stick.
- 3While the onions caramelize, bring a pot of salted water to a boil and cook the pasta until al dente. Drain, reserving some pasta water.
- 4When the onions are deeply golden, stir in the minced garlic and all the seasonings. Cook for about a minute, then add the chili crisp and sauté for another minute.
- 5Pour in the cream (or coconut milk) and let it simmer for a few minutes. Stir in the grated Parmesan cheese until melted and the sauce is smooth.
- 6Add the cooked pasta to the sauce and toss to coat, using reserved pasta water as needed to achieve a silky consistency.
- 7Serve hot, topped with an extra spoonful of chili crisp and, if desired, a sprinkle of fresh parsley.
