The Ingredient Line-Up

Here’s what you’ll need to whip up this cheesy masterpiece:

The Caramelized Onions

• 2 medium yellow onions (yellow onions caramelize best)
• 2 tablespoons olive oil
• 2 tablespoons butter
• A pinch of salt and pepper

The Mac and Cheese

• 16 oz elbow macaroni (or your favorite pasta shape)
• ½ cup butter
• ½ cup all-purpose flour
• 2 cups whole milk
• 1 cup beef stock
• 2 cups Gruyere cheese, shredded
• 1 cup mozzarella cheese, shredded
• 2 cups shredded chicken (rotisserie chicken works great)
• 1 teaspoon garlic powder
• ½ teaspoon mustard powder
• A dash of cayenne pepper (optional)

The Topping

• ¼ cup Gruyere cheese (more cheese = better)
• Fresh thyme for garnish (optional)

Step-by-Step Directions

Caramelize the Onions

This is the foundation of the dish. Don’t rush it—good things take time.

1. Heat olive oil and butter in a skillet over medium heat.
2. Toss in your sliced onions and stir to coat them in that buttery goodness.
3. Reduce the heat, cover, and let the onions cook for about 25-30 minutes, stirring occasionally.
4. When they’re golden brown and sweet, season with salt and pepper. Set them aside—you’ll thank yourself later.

Make the Creamy Cheese Sauce

This sauce is pure magic. Creamy, cheesy, and downright addictive.

1. In a large saucepan, melt the butter over medium heat.
2. Whisk in the flour and cook for a minute or two to eliminate the raw flour taste.
3. Gradually add the milk and beef stock, whisking constantly until it thickens.
4. Remove from heat and stir in the Gruyere and mozzarella until it’s smooth and melty. Add the garlic powder, mustard powder, and cayenne for extra flavor.

Bring It All Together

1. Cook your pasta according to the package directions until it’s al dente. Drain and toss it into the cheese sauce.
2. Stir in the shredded chicken and caramelized onions. Mix until every noodle is coated in cheesy goodness.

Bake It to Perfection

1. Pour the mixture into a greased baking dish and spread it out evenly.
2. Top with extra Gruyere cheese for that golden, bubbly finish.
3. Bake at 350°F for 15 minutes, or until the top is golden and irresistible.
4. Garnish with fresh thyme and serve immediately.

Tips for Making It Even Easier

• Short on time? Grab pre-cooked caramelized onions from the store. It’s a lifesaver when you’re in a rush.
• No Gruyere? No worries. Swiss, Fontina, or sharp cheddar can step in.
• Make-ahead option: Assemble the whole dish, cover it, and stash it in the fridge. Bake it fresh when you’re ready to eat.

What to Serve With It

This dish is rich and satisfying on its own, but if you’re looking to round out your meal:

• A crisp green salad with a tangy vinaigrette.
• Roasted veggies like asparagus or Brussels sprouts.
• Garlic bread—because carbs on carbs are always a good idea.

Leftovers? Lucky You.

Alright, let’s talk about leftovers. French Onion Chicken Macaroni and Cheese isn’t just a one-hit wonder—it’s the gift that keeps on giving. Honestly, I think it might even taste better the next day. The flavors have more time to mingle, the cheese somehow feels even creamier, and, let’s face it, leftover mac and cheese is always a win.

Here’s how to keep it tasting just as incredible as the first time you served it.

Refrigerate Like a Pro

If you’re planning to dive back in within the next few days (and let’s be honest, you probably are), pop those leftovers in an airtight container.

• How Long? They’ll stay fresh for up to 4 days in the fridge.
• Pro Tip: Make sure to let it cool to room temp before storing—it helps prevent condensation from making things soggy.

Freeze It for Later

Want to save some for a rainy day—or, let’s be real, a lazy Sunday? Freezing is the way to go. Here’s how to do it without sacrificing that creamy, cheesy goodness:

1. Divide It: Portion it out into freezer-safe containers or heavy-duty freezer bags. Smaller portions make reheating a breeze.
2. Label It: Write the date on the container, so you know when you stashed it away.
3. Freeze It: Store for up to 3 months.

• Pro Tip: If you have a vacuum sealer, use it! It helps prevent freezer burn and keeps the cheese sauce smooth when reheated.

Reheat Like a Boss

When you’re ready to enjoy those leftovers, reheating is an art. The goal? Keep it creamy, cheesy, and just as irresistible as it was fresh out of the oven.

1. Add a Splash of Milk: Whether you’re microwaving or using the oven, stir in a little milk to bring back that silky texture.
2. Microwave Method: Cover your portion with a microwave-safe lid and heat in 30-second bursts, stirring in between, until warmed through.
3. Oven Method: Place your leftovers in an oven-safe dish, add a splash of milk, cover with foil, and bake at 350°F for about 20 minutes. Stir gently before serving.

• Pro Tip: Toss a little fresh cheese on top before reheating in the oven for that melty, golden-brown finish all over again.
