Ingredients

• 2 tablespoons extra virgin olive oil (high-quality oil enhances flavor)
• 2 medium yellow onions, very thinly sliced (Vidalia onions are a sweet option)
• Water to deglaze the pan (helps lift those flavorful brown bits)
• 4 garlic cloves, thinly sliced (adds aromatic richness)
• Kosher salt or sea salt to taste
• Freshly cracked black pepper to taste
• 1 teaspoon red pepper flakes (for a touch of heat)
• 1 teaspoon dried oregano (adds earthy flavor)
• 1 5.3 ounce (150g) tube of tomato paste (brings depth and body)
• 2 tablespoons tamari (or soy sauce) (for umami)
• 2 tablespoons nutritional yeast (gives a cheesy flavor)
• 4 to 5 large oil-packed sundried tomatoes, finely chopped (richly flavorful)
• 10 ounces (285g) spaghetti or linguine (choose whole grain for extra nutrition)
• Toasted pine nuts (optional garnish) (adds a delightful crunch)
• Chopped flat-leaf Italian parsley (optional garnish) (for freshness)

Prep Notes: If your pasta is stored in the fridge, allow it to come to room temperature before cooking. Choosing fresh, high-quality ingredients will elevate the dish significantly!

Step-by-Step Instructions

1. Boil Pasta: Bring a large saucepan of salted water to a boil. Generously salt the water—this will flavor the pasta. Add the spaghetti or linguine and cook according to package instructions until al dente, usually about 8-10 minutes.

2. Reserve Pasta Water: Before draining the pasta, scoop out at least 1 cup of pasta water and set it aside. This starchy water is perfect for adjusting the sauce’s consistency.

3. Caramelizing Onions: In a large skillet or Dutch oven, heat the olive oil over medium-high heat. Add the sliced onions and season with salt and pepper. Sauté for about 5 minutes until they begin to soften, adding a splash of water to deglaze the pan if needed.

4. Deepen Flavors: Continue cooking the onions, stirring frequently, for an additional 15 minutes until they’re deeply golden brown and deeply flavorful. Add the sliced garlic and cook, stirring, for another 5-10 minutes until caramelized.

5. Build Flavor: Add the red pepper flakes and oregano, stirring for about 30 seconds. Incorporate the tomato paste and cook for 2-3 minutes until it darkens and caramelizes slightly.

6. Combine Ingredients: Stir in the tamari, nutritional yeast, and sundried tomatoes. Reduce the heat to low and stir to combine. This will create a rich and savory sauce.

7. Create the Sauce: Gradually add some of the reserved pasta water, about 1/4 cup at a time, keeping the sauce loose and silky. Toss the cooked pasta directly into the skillet, coating it well with the sauce.

8. Garnish and Serve: Garnish with toasted pine nuts and chopped parsley if desired. Serve immediately and savor each bite. Store any leftovers in an airtight container for 2-3 days.

Chef’s Tips: Make sure your onions are sliced evenly for uniform cooking. Avoid the urge to rush the caramelization process; patience is key to developing those lovely flavors.

Expert Tips & Tricks

• Onion Secrets: If you find that the onions are browning too quickly, lower the heat and add a splash more water. This will help them cook evenly without burning.

• Storage Recommendations: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove with a little added pasta water to loosen the sauce.

• Make-Ahead Instructions: You can caramelize the onions ahead of time and store them in the fridge. Just reheat before adding the pasta.

• Troubleshooting: If your sauce ends up too thick, gradually add more pasta water until it reaches your desired consistency. If it’s too thin, let it simmer a bit longer.

Serving Suggestions

Pair this delicious Caramelized Onion Pasta with a simple arugula salad tossed in lemon vinaigrette for brightness. A glass of chilled white wine or sparkling water adds the perfect touch! For a cozy night in, serve it with garlic bread to soak up the luscious sauce.
