How to Make It
1. Cook the Macaroni
Start by cooking your macaroni according to the package instructions until al dente. This means it should still have a slight bite to it. Drain and set aside, letting it cool slightly. The cooking smell alone is a cozy reminder of home!
2. Caramelize the Onions
In a skillet, melt 2 tablespoons of butter over medium heat. Add the sliced onions and cook for 15-20 minutes, stirring occasionally, until they are golden brown and fragrant. The transformation is magical as they turn sweet and jammy!
3. Make the Cheese Sauce
In a separate saucepan, melt another tablespoon of butter over medium heat. Whisk in the flour to form a roux, stirring for about a minute until smooth. Gradually add the milk, stirring continuously until thickened. Season with salt, pepper, garlic powder, and thyme — the aromas will have you swooning!
4. Add the Cheese
Stir in the shredded cheese until it melts into a creamy, gooey goodness. Keep tasting — you want it to sing!
5. Combine Everything
In a baking dish, combine the cooked macaroni, caramelized onions, and luscious cheese sauce. If you’re feeling wild, sprinkle with breadcrumbs for that delightful crunchy topping.
6. Bake to Perfection
Preheat your oven to 350°F (175°C) and bake for 20-25 minutes until it’s bubbly and golden brown. When you pull it out, the scent will be heavenly, and the crust will look absolutely inviting!
Pro Tips for Success
- For a kick of heat, add some crumbled red pepper flakes to the cheese sauce.
- Don’t rush the caramelization of the onions; low and slow is key to their sweetness!
- Mixing cheeses can create a unique flavor; feel free to experiment!
- Use a combination of different pasta shapes for a fun twist.
Flavor Variations
- Try swapping the shredded cheeses! Fontina or mozzarella would be great alternatives, or go bold with a blue cheese twist.
- Seasonal veggies like spinach or mushrooms can be sautéed with the onions for an added freshness.
- Spice things up with a dash of smoked paprika or cumin for a different flavor profile.
Serving Suggestions
Pair this comforting dish with a light salad dressed in a tangy vinaigrette to offset the rich cheese. Some crusty bread or soft dinner rolls will be perfect for soaking up the cheesy goodness! A nice glass of white wine can also elevate the experience, making it a cozy night in!
Make-Ahead & Storage
This recipe is fantastic to prep ahead. Simply assemble everything and refrigerate (without baking) for a day or two. When ready to bake, just pop it in the oven directly — no need to thaw!
Leftovers will keep in the fridge for about 3-4 days, just make sure it’s sealed well.
Leftovers
Don’t let those delicious leftovers go to waste! Add a touch of milk and reheat in a skillet for a creamy pasta dish, or toss it into a frittata for a mouthwatering breakfast!
Freezing
Yes, you can absolutely freeze this dish! Just transfer it to an airtight container, let it cool completely, and freeze for up to 3 months. When you’re ready to enjoy, thaw in the refrigerator overnight before baking.
Reheating
The best way to reheat is in the oven for that lovely, crisp topping! Cover with foil to prevent over-browning — about 20 minutes at 350°F (175°C) should do the trick. The microwave is quick and easy, but don’t blame me if the top isn’t as crispy!
FAQs

Absolutely! Just use your favorite gluten-free pasta and follow the same instructions!
Is it possible to double this recipe?
For sure! Just use a larger baking dish and keep an eye on the baking time since it might take longer to heat through.

While cheddar and Gruyère are perfection, feel free to experiment with any meltable cheese you have on hand!
