Ingredients
This pasta dish proves that fewer ingredients can lead to deeper, more developed flavors. Here’s what you’ll need:
For 2 servings:
- 200 g (7 oz) dry spaghetti
- 3 large yellow onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter (optional, for extra richness)
- 1 teaspoon chili flakes (adjust to taste)
- Salt and freshly ground black pepper to taste
- Fresh parsley (optional, for garnish)
- Grated Parmesan or Pecorino Romano (optional)
Optional Add-ons:
- 2 cloves garlic, minced (for an aromatic boost)
- A squeeze of lemon juice (for acidity)
- Toasted breadcrumbs (for extra texture)
Kitchen Tools Needed
This recipe is beginner-friendly and doesn’t require special equipment. Here’s what you’ll need:
- 1 large pot for boiling pasta
- 1 large skillet or sauté pan (preferably nonstick or stainless steel)
- Tongs or a pasta spoon
- A sharp knife and cutting board
- Optional: Microplane grater (for cheese or lemon zest)
Step-by-Step Preparation
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente, following package instructions. Reserve 1/2 cup of the pasta water before draining.
Step 2: Caramelize the Onions
In a large skillet, heat the olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 20–25 minutes until deeply golden and caramelized. You want them soft, sweet, and slightly sticky. If they start to dry out, add a splash of water.
Tip: Low and slow is the key. Rushing the onions will brown them, not caramelize them.
Step 3: Add Chili Flakes and Optional Garlic
Once the onions are caramelized, stir in the chili flakes and optional garlic. Cook for 1 minute, just until fragrant. Turn off the heat if the garlic starts to brown.
Step 4: Combine Pasta and Sauce
Add the drained spaghetti directly into the skillet with the onions. Toss everything together, adding reserved pasta water as needed to loosen the mixture and help the flavors coat the pasta.
Step 5: Finish and Serve
Add butter (if using) for richness, season with salt and black pepper to taste, and serve immediately. Garnish with chopped parsley, lemon zest, or grated cheese as desired.
Helpful Tips
- Don’t rush the onions. Caramelization is where the magic happens. It’s the depth of flavor that elevates this dish.
- Control the heat. If you’re sensitive to spice, reduce the chili flakes or replace them with sweet paprika for flavor without heat.
- Balance the flavors. A small squeeze of lemon juice or splash of vinegar at the end can cut the richness and brighten the dish.
- Make it a full meal. Add sautéed mushrooms, wilted spinach, or crispy chickpeas for protein and variety.
