How to Make French Onion Mac and Cheese

Step 1: Caramelize the Onions

Start by heating the olive oil in a large oven-safe skillet over medium heat. Stir in the sliced onions along with a generous pinch of salt. Cooking them slowly allows their natural sugars to caramelize beautifully, resulting in those golden-brown gems that add depth to your dish.

Step 2: Create the Roux

Once your onions are perfectly caramelized (this takes time but trust me, it’s worth it!), transfer them to a plate. In the same skillet, melt butter over medium heat before whisking in flour to form a roux. This will thicken your cheese sauce beautifully!

Step 3: Prepare the Cheese Sauce

Gradually pour in milk while stirring continuously until everything thickens into creamy perfection. Adding nutmeg enhances the overall flavor profile — it’s like giving your sauce a warm hug!

Step 4: Combine Pasta & Onions

Mix in most of the grated cheese until melted, then fold in those delicious caramelized onions along with your cooked pasta. Toss everything together until each piece is coated in cheesy goodness.

Step 5: Bake to Perfection

Top your mixture with remaining cheese, onions, and sprinkle seasoned bread crumbs on top. Baking it allows all those flavors to meld together while creating that coveted crispy top layer — so satisfying!

Step 6: Serve & Enjoy!

After baking until bubbly and golden brown, remove from the oven and garnish with fresh thyme. Serve hot and watch as everyone digs into this delightful twist on comfort food!

• Don’t Rush the Caramelization: Taking your time to slowly caramelize the onions allows their sugars to develop fully, creating a rich, deep flavor that elevates your mac and cheese.

• Shred Your Cheese Fresh: Grating cheese yourself leads to better melting and a smoother sauce compared to pre-shredded varieties, which often contain anti-caking agents.

• Reserve Pasta Water: Keeping a cup of pasta water before draining helps adjust the consistency of your cheese sauce later. If it’s too thick, just stir in a little pasta water until you reach your desired creaminess.
