Caramelized Onion & Garlic Spaghetti
This caramelized onion and garlic spaghetti is a simple yet flavor-packed pasta dish made with slow-cooked onions, fragrant garlic, and perfectly cooked spaghetti tossed until glossy and rich.
Ingredients
- 8 oz Spaghetti or pasta of your choice
- 1 large onion thinly sliced
- 4 garlic cloves minced
- 2 tablespoon butter
- 1 tablespoon olive oil
- 2 tablespoon chili crisp
- 1 cup heavy whipping cream or coconut milk room temperature
- 1 tablespoon soy sauce optional
- ½ cup fresh Parmesan cheese grated
- 1 teaspoon Smoked Paprika
- 1 teaspoon Garlic powder
- 1 teaspoon Onion Powder
- 1 teaspoon Season Salt
- 1 teaspoon Black pepper
- 1 teaspoon Chili Powder
- 1 teaspoon Italian seasoning
- Reserved pasta water as needed
- Optional garnish: Extra chili crisp and Fresh parsley
Instructions
- Slice the onion thinly and mince the garlic. Measure out all seasonings. Bring the cream or coconut milk to room temperature.
- Heat the butter and olive oil together in a large skillet over medium heat.
- Add the sliced onions and cook for 15 to 20 minutes, stirring occasionally, until deeply golden and jammy. If the onions start sticking, add a small splash of water and continue cooking.
- While the onions cook, bring a pot of well salted water to a boil. Cook the pasta until al dente. Drain and reserve some of the pasta water.
- Once the onions are deeply caramelized, add the minced garlic and all the seasonings. Stir and let everything bloom for about 1 minute.
- Stir in the chili crisp and sauté for another minute.
- Pour in the cream or coconut milk and add the soy sauce if using. Let the sauce simmer gently for a few minutes until warmed and slightly thickened.
- Stir in the grated Parmesan cheese until melted and smooth.
- Add the cooked pasta directly to the skillet. Toss to coat, adding reserved pasta water a little at a time until the sauce is silky and coats the pasta without being thick or sticky.
- Serve hot. Top with an extra spoon of chili crisp and fresh parsley if desired.
