Ingredients You’ll Need

• Dry Marsala – adds depth (or use white wine or cooking wine)

• Beef stock + water – for cooking the pasta and building the broth

• Beef base – optional, enhances umami (use vegetarian base if needed)

• Bay leaves, salt & pepper – classic seasoning

• Short pasta – such as rigatoni, orecchiette, or farfalle

• Gruyère + parmesan cheese – French onion staples

• Heavy cream – finishes the sauce with richness

Vegetarian? Use mushroom, roasted garlic, or “no-beef” base with veggie broth.

How to Make It

Step 1: Caramelize the Onions

In a large Dutch oven, heat butter and olive oil over medium. Add sliced onions and a generous pinch of salt. Stir occasionally and cook for 45–50 minutes until deeply golden and caramelized. Add splashes of water as needed to prevent sticking.

Step 2: Build the Flavor Base

Add garlic and thyme, cooking for 1–2 minutes. Deglaze with Marsala wine. Stir in beef stock, water, bay leaves, salt, pepper, and beef base. Bring to a boil.

Step 3: Cook the Pasta

Add uncooked pasta. Simmer uncovered over medium heat, stirring occasionally until al dente and most of the liquid is absorbed.

Step 4: Add Cheese and Cream

Remove from heat. Stir in Gruyère and parmesan until melted. Add cream and mix well. Let rest for 5–10 minutes to allow the sauce to thicken before serving.

Tip: Garnish with more cheese and fresh thyme for presentation.

Make-Ahead Tip

Caramelizing onions is time-consuming—but you can prep them in advance.
✅ Cook onions through deglazing step and refrigerate for up to 5 days or freeze for 2–3 months.
✅ When ready, reheat with stock and proceed with the recipe as written.
