Ingredients
Scale
Pasta
- 2 servings spaghetti (or your favorite pasta)
Sauce
- 2 tbsp chili oil
- 1/2 cup cream
- 1 large red onion, thinly sliced
- 3 tbsp olive oil
- 3–4 garlic cloves, finely chopped
- 1 tbsp Italian seasoning
- Salt to taste (about 1–2 tsp)
Optional Garnishes
- Parmesan cheese
- Chopped parsley for garnish
Instructions
- Prepare the Ingredients: Slice the red onion thinly and finely chop the garlic to prepare for cooking.
- Cook the Pasta: Bring a pot of water to a boil, add 2 tsp of salt, and cook the spaghetti according to package instructions. Reserve 1 cup of pasta water before draining to adjust sauce consistency later.
- Caramelize the Onions: Heat 3 tbsp olive oil in a pan over medium heat. Add the sliced onions and cook for 6–7 minutes, stirring occasionally, until golden and caramelized, developing a sweet flavor base.
- Add Garlic and Chili Oil: Stir in the chopped garlic and sauté for 1–2 minutes until fragrant. Add the chili oil and mix well to infuse the sauce with heat and aroma.
- Make the Sauce: Lower the heat and pour in the cream, then add the Italian seasoning and salt to taste. If the sauce is too thick, loosen it by adding a splash of reserved pasta water and stir until smooth.
- Combine with Pasta: Add the cooked pasta to the pan and toss thoroughly until the pasta is evenly coated with the creamy, spicy sauce.
- Garnish and Serve: Top with grated Parmesan cheese and chopped parsley if desired. Serve immediately for the best flavor and texture.
Notes
- Adjust Spice Level: Use less chili oil for a milder version or add more for extra heat.
- Make It Vegan: Substitute cream with coconut cream or another dairy-free alternative, and use vegan Parmesan cheese.
- Protein Options: Add grilled chicken, shrimp, or crispy pancetta to make the dish heartier.
- Storage Tip: Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently with a splash of water or cream to maintain sauce creaminess.
