How to Make French Onion Soup Mac & Cheese
-
Preheat the oven to 375°F (190°C). Use a little butter to grease your favorite baking dish, ensuring the glorious cheesy goodness won’t stick!
-
Caramelize the onions by heating olive oil and 1 tablespoon of butter in a large skillet over medium heat. Stir them often for about 25-30 minutes until they are beautifully golden and sweet. Add in garlic and fresh thyme for added flavor in the last few minutes.
-
Create a roux by adding the remaining butter to the skillet. Sprinkle in the flour, stirring constantly until combined. Gradually whisk in vegetable broth, then the milk and cream until the mixture is smooth and thickens slightly.
-
Melt the sensation by stirring in the Gruyère, cheddar, and mozzarella cheeses until they are all perfectly melted. Season this indulgent mixture with salt and black pepper to taste. Toss in the al dente macaroni, folding it gently with the onions and sauce until well-coated.
-
Transfer the creamy noodle mixture into your buttered baking dish. For that irresistible crunchy topping, sprinkle a mix of breadcrumbs and grated Parmesan over the surface.
-
Bake for 20-25 minutes until it’s bubbly and the top is golden brown. This is when the mouthwatering scent will have your family eagerly anticipating dinner!

Let rest for 5 minutes before serving. Garnish with extra thyme leaves for a pop of freshness, then dig in while it’s hot.
Optional: Serve with a light side salad to balance the richness!

Make Ahead Options
These French Onion Soup Mac & Cheese are a fantastic choice for meal prep, perfect for bustling weeknights! You can caramelize the onions and prepare the cheese sauce up to 24 hours in advance. Simply store each component in an airtight container in the refrigerator, ensuring that the cheese stays creamy (the sauce can thicken slightly, so a splash of milk can help when reheating). When you’re ready to serve, cook your pasta and combine everything before transferring it to the baking dish. Top with breadcrumbs mixed with Parmesan and bake it straight from the fridge, adding an extra 5-10 minutes to the cooking time for deliciously golden results that taste just as good as freshly made!
Expert Tips for French Onion Soup Mac & Cheese
• Caramelization Matters: Take your time when caramelizing the onions; it’s key to developing that rich flavor. Don’t rush this step for the best taste!
• Cheese Choices: Experiment with different cheese combinations. While Gruyère and cheddar work wonderfully, try Havarti or fontina for a unique twist!
• Avoid Overcooking Pasta: Cook the elbow macaroni just until al dente. Remember, it will continue cooking as it bakes with the cheese sauce.
• Roux Consistency: Ensure your roux is cooked enough by stirring until it turns a light golden color; this prevents a raw flour taste.
• Serving Ideas: Pair with a fresh side salad for a balanced meal. Adding a light herb vinaigrette can elevate the experience even further!
These tips will help you create the most mouthwatering French Onion Soup Mac & Cheese that your family will crave!
