Main Ingredients
- 4 large yellow onions, thickly sliced
- 3 tablespoons olive oil or butter
- 12 ounces pasta of choice (rigatoni, fettuccine, penne recommended)
- 3 cloves garlic, minced
- 1/2 cup freshly grated Parmesan cheese
- Salt, to taste
- Freshly ground black pepper, to taste
Optional Ingredients
- Fresh herbs such as basil or thyme, chopped, for garnish
- Red pepper flakes for a spicy kick
- Grilled chicken, crispy bacon, or sautéed mushrooms for protein boost
- Plant-based butter and vegan cheese for a vegan variation
- Toasted pine nuts or walnuts for added crunch
- Prepare the Onions: Peel and slice the onions into thin, even strips. Heat olive oil or butter in a large pan over medium-low heat. Add the onions and stir occasionally. Cook slowly for 30-40 minutes until they become deeply golden, soft, and sweet.
- Cook the Pasta: While onions caramelize, bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Drain and reserve 1 cup of pasta water.
- Add Garlic and Combine: Add minced garlic to the caramelized onions and cook gently for 1-2 minutes until fragrant. Toss in the drained pasta and stir well to coat it with the onion mixture. Use reserved pasta water to loosen sauce if needed.
- Finish with Cheese and Season: Sprinkle freshly grated Parmesan cheese over the pasta. Stir to create a creamy coating. Season generously with salt and freshly ground black pepper, adjusting to taste.
- Garnish and Serve: Add freshly chopped herbs like basil or thyme for freshness. Serve immediately while warm and aromatic.
Notes
- Cook onions low and slow to fully develop their sweetness without burning.
- Use a wide pan to allow the onions to cook evenly and avoid sogginess.
- Reserve pasta water to create a silky sauce that binds well to the pasta.
- Season gradually to avoid oversalting; adjust seasoning at the end.
- Use freshly grated Parmesan cheese for the best melt and flavor.
