Description
A rich and comforting pasta dish featuring sweet caramelized onions and garlic in a savory cream sauce.
Ingredients
- 12 ounces dry spaghetti pasta
- 3 medium white onions, halved and thinly sliced
- 1 cup heavy whipping cream
- 1/2 cup vegetable broth
- 8 cloves garlic, minced
- 5 tablespoons unsalted butter
- 2 tablespoons grated Parmesan cheese
- 1 tablespoon extra-virgin olive oil
- 1 teaspoon white sugar
- 1/2 teaspoon salt
- Freshly cracked black pepper to taste
Instructions
- Melt the butter and olive oil in a saucepan over low heat. Add the sliced onions, minced garlic, sugar, and salt. Cover and cook for roughly 20 minutes, stirring occasionally, until the onions are very soft and translucent.
- Meanwhile, bring a large pot of salted water to a boil. Cook the spaghetti for about 7 to 8 minutes until al dente. Drain the pasta and keep it warm.
- Pour the vegetable broth into the onion mixture. Increase heat to bring to a boil, then reduce to low and simmer for 2-3 minutes until the liquid reduces and evaporates.
- Stir in the heavy cream and simmer for 2 minutes until the sauce slightly thickens.
- Place the cooked spaghetti in a serving bowl. Pour the hot onion cream sauce over the pasta. Add the Parmesan cheese and black pepper, then toss well to coat every strand.
Notes
For a lighter version, you can substitute half-and-half for the heavy cream, though the sauce will be less thick. If you don’t have vegetable broth, chicken broth works well for non-vegetarians.
