Instructions

Let’s dive into the steps to create this comforting French Onion Pasta:

Preheat Your Equipment: Bring a large pot of salted water to a boil for the pasta. Preheating is essential to ensure perfect al dente texture.

Caramelize the Onions: Slice the onion thinly. In a large skillet, heat olive oil and butter over medium-low heat. Add onions, salt, pepper, and thyme. Cook slowly, stirring occasionally, until deep golden brown — about 20–25 minutes. Add garlic in the final 2 minutes to prevent burning.

Deglaze the Pan: Add balsamic vinegar, tamari, and white wine to the caramelized onions. Stir, scraping up any fond from the pan. Let it simmer for a few minutes until the liquid reduces slightly.

Make the Roux & Sauce: Sprinkle flour over the onion mixture and stir well to form a smooth paste. Gradually whisk in vegetable stock, ensuring there are no lumps. Add cream and cook until sauce thickens and coats the back of a spoon.

Cook the Pasta: While making the sauce, cook farfalle in boiling water until just al dente. Drain and reserve a little pasta water.

Combine Pasta and Sauce: Add cooked pasta to the skillet, tossing gently to coat in the creamy onion sauce. If needed, add a splash of pasta water to loosen the sauce.

Add Cheese: Stir in most of the grated cheddar, reserving some for topping. The cheese melts into the sauce, creating a luscious, gooey texture.

Serve and Enjoy: Plate your French Onion Pasta, sprinkle remaining cheddar on top, and garnish with fresh thyme if desired. Serve warm and savor every rich, creamy, cheesy bite.
