Ingredients: What You’ll Need
Essential Ingredients

- Dry White Wine (1/2 cup): Helps deglaze and enhance onion flavor.
- Vegetable or Chicken Broth (2 cups): Forms the base of the sauce.
- Evaporated Milk (1 cup) + Cornstarch (1 tbsp): Creates a silky, clingy sauce without heavy cream.
- Worcestershire & Soy Sauce (1 tsp each): Secret umami boosters that deepen savory complexity.
- Bay Leaf & Fresh Thyme (1 each): Add fragrant herbal notes.

Pro Tips Before You Start
- Caramelize Low & Slow: Cook onions over medium-low heat for 15–20 minutes. This develops a rich, deep sweetness without burning.
- Deglaze Thoroughly: Scrape up the fond (the brown bits) after adding wine; this is flavor gold.
- Reserve Pasta Water: A splash of starchy water can help loosen a thick sauce and help it cling to noodles.
- Broiler Safety: Use an oven-safe skillet or transfer to a baking dish to finish the cheese layer.
- Fresh Herbs Matter: Sprinkle parsley or extra thyme before serving for freshness and color.
Step-by-Step Instructions
Step 1: Caramelize the Onions
- Heat olive oil and butter in a large, oven-safe skillet over medium-low heat.
- Add thinly sliced onions with a pinch of salt.
- Stir frequently, letting them cook for 15–20 minutes until they reach a deep golden-brown color.
- Optional: Add mushrooms halfway through if using.
Step 2: Build the Sauce
- Increase heat to medium. Pour in white wine and deglaze, scraping up the brown bits from the pan.
- Stir in broth, evaporated milk (mixed with cornstarch), Worcestershire, soy sauce, bay leaf, and thyme.
- Simmer gently for 5–7 minutes, allowing flavors to meld.
Step 3: Cook the Pasta
- Boil pasta in salted water until al dente. Drain, reserving 1/2 cup pasta water.
- Toss pasta into the onion-wine sauce. Use reserved pasta water to adjust sauce consistency.
Step 4: Cheese & Broil
- Sprinkle shredded cheese evenly over the pasta.
- Place under the broiler for 2–4 minutes, until bubbly and golden.
- If you don’t have a broiler, stir in cheese off heat for a creamy finish.
Step 5: Serve & Garnish
- Remove bay leaf and thyme sprigs.
- Garnish with fresh parsley or thyme.
- Serve immediately with a crisp side salad, crusty bread, or roasted vegetables.

2. Protein Add-In

3. Dairy-Free
Swap evaporated milk with coconut or cashew cream and use plant-based cheese.
4. Herb Swap
Replace thyme with rosemary or sage for a more aromatic profile.
5. Pasta Swap
Short shapes like penne, shells, or cavatappi create pockets for the sauce and cheese.
Storage & Reheating Tips
- Refrigerate: Store leftovers in an airtight container for up to 3 days. Reheat gently with a splash of broth to restore creaminess.
