French Onion Pasta Recipe: Creamy Caramelized Onion Noodle Bake

French Onion Pasta is a comforting, savory one-skillet meal. Slowly caramelized onions lend deep sweet and savory notes to a creamy pasta sauce. I like to add chicken for a complete meal, but the dish is equally delicious vegetarian.

Why Make French Onion Pasta

This is an ideal recipe when you want a simple, satisfying dinner that feels cozy. Everything cooks in one skillet and the caramelized onions bring a rich, layered flavor with a touch of sweetness that pairs beautifully with creamy sauce and your choice of protein.

• Easy. A straightforward one-pan recipe — the longest step is patiently caramelizing the onions.
• Flavorful. Caramelized onions give a deep, savory-sweet base to the dish.
• Flexible. Keep it vegetarian or add chicken, shrimp, or steak. You can also swap ingredients to suit dietary needs.

Ingredient Notes

Full ingredient amounts are listed in the recipe card below.

• Chicken breasts. Optional — adds protein if you want a heartier meal.
• Yellow onions. Best for caramelizing; they balance sweet and savory flavors well.
• Olive oil. Used to cook the onions and sear the chicken.
• Garlic & seasonings. Garlic, salt, pepper, thyme, and dried parsley or basil for garnish.
• Flour. All-purpose flour thickens the sauce; use a gluten-free substitute if needed.
• Sherry wine vinegar. Adds brightness when deglazing; lemon juice can be used as a substitute.
• Beef broth. Forms the base of the sauce and helps cook the pasta.
• Worcestershire sauce. Adds umami depth to the sauce.
• Pasta. Any shape works; bowtie (farfalle) is a favorite here.
• Cream. A splash of heavy cream or whole milk creates a silky finish.
• Breadcrumbs. Optional toasted breadcrumbs make a crunchy topping.

Recipe Variations

• Vegetarian: Omit chicken and add sautéed mushrooms or roasted vegetables.
• Dairy-free: Skip the cream or use a plant-based alternative.
• Elevated: Add bacon or pancetta for a smoky boost.

Steps To Make This Recipe

• Step One. If using chicken, season with salt and pepper and cook by your preferred method. In a skillet, cook about 12 minutes per side until internal temperature reaches 165ºF, or until done to your liking. Remove and chop for later.
• Step Two. Heat olive oil in a large, deep-sided skillet over medium heat. Add the thinly sliced onions and a generous pinch of salt. Reduce heat to medium-low and cook, stirring frequently, until the onions are deeply browned and caramelized — about 30–40 minutes depending on thickness. Patience here builds the best flavor.
• Step Three. Add minced garlic and thyme; sauté 1–2 minutes. Pour in sherry wine vinegar to deglaze the pan, scraping up any browned bits. Stir in the flour and cook 2–3 minutes until it thickens slightly.
• Step Four. Pour in beef broth, Worcestershire sauce, and water. Season with salt and freshly ground black pepper. Add the pasta, bring to a simmer, and cook 10–12 minutes or until al dente, stirring occasionally. Depending on pasta shape and brand, you may need an additional 1/4–1/2 cup water or broth if the pasta absorbs liquid too quickly.
• Step Five. Taste and adjust seasoning as needed. Stir in the cream and chopped chicken (if using). Garnish with dried parsley and toasted breadcrumbs if desired. Serve warm.

Recipe Pairings

This rich pasta pairs well with lighter vegetable sides to balance the meal. Try roasted broccoli, parmesan-crusted Brussels sprouts, roasted potatoes, or a simple mixed green salad for a complete dinner.
