Prep and cook Time

• Prep Time: 15 minutes
• Cook Time: 1 hour 15 minutes (mostly unattended)

Yield

Serves 4 generous portions

Difficulty Level

Medium – precise patience creates big rewards!

Ingredients

• 4 large yellow onions, thinly sliced
• 3 tbsp unsalted butter
• 2 tbsp extra-virgin olive oil
• 1 tsp fine sea salt
• 1/2 tsp freshly ground black pepper
• 1 tbsp balsamic vinegar (optional for extra depth)
• 12 oz dried fettuccine or tagliatelle pasta
• 1/2 cup freshly grated Parmesan cheese
• 2 cloves garlic, finely minced
• Fresh thyme sprigs or chopped flat-leaf parsley for garnish

Instructions

1. Choose and prepare your onions. Opt for yellow onions,prized for their balanced sweetness and low pungency ideal for caramelization.Peel and slice evenly into thin half-moons to ensure uniform cooking.
2. Warm your pan over medium-low heat. Add butter and olive oil-the blend prevents burning and promotes even caramelization. Once melted and shimmering, add onions.
3. Sprinkle salt evenly. This draws moisture out, accelerating the breakdown of onions’ fibers while softening texture.
4. Cook low and slow. Sauté onions, stirring every 5-7 minutes to prevent sticking or burning. Patience is critical here-true caramelization quietly unfolds over 60-75 minutes, allowing natural sugars to deepen into a rich amber color.
5. About halfway through, add minced garlic. Garlic melds with the natural sweetness, infusing the mix without overwhelming.
6. Finish with balsamic vinegar if desired, a subtle layer of acidity that lifts and balances residual richness.
7. Meanwhile, bring salted water to a boil. Cook pasta just shy of al dente as it will finish cooking while combined with onions. reserve ½ cup pasta water before draining.
8. Combine pasta with warm caramelized onions in the pan, stirring over low heat. Add reserved pasta water gradually for silkier consistency and to help sauce cling.
9. Plate and sprinkle with freshly grated Parmesan and a sprinkle of fresh thyme or parsley. A crack of black pepper enhances aromatic complexity.

Chef’s Notes: Tips for Success

• Patience is key – rushing the caramelization at high heat results in bitter, burnt onions rather than sweet depth.
• Yellow onions work best; avoid white onions (too sharp) or red onions (too mild for this technique).
• Maintain low heat-adjust to avoid browning too quickly. The process may take over an hour but yields unparalleled sweetness.
• Use a wide, heavy-bottomed skillet for optimal moisture evaporation and even browning.
• Make ahead: caramelized onions can be refrigerated for up to 5 days or frozen, making meal prep effortless.
