Author’s Notes

Even My Onion-Hating Husband Loved It

Let me start by saying my husband is one of the least picky eaters I’ve ever met. But there’s one food he truly can’t stand: onions. He won’t touch them raw, and even cooked, they have to be diced super fine and completely soft before he’s okay with them. Soooo French onion soup? Way too many onions for him!

So when I made this, I honestly didn’t think he’d like it. I figured he’d pick around the onions and move on. But I was so surprised when he started raving about how good it was! He did pick around most of the bigger onion pieces, but he couldn’t stop talking about how rich the flavor was and how creamy and cheesy the pasta turned out. If I can get an onion hater to love this dish, you know it’s good!

French Onion Mac and Cheese Ingredients

IngredientHelpful Tip
Onions, Garlic, Butter, Thyme, Worcestershire, BouillonSlice onions very thin (use a mandoline if you have one!) so they caramelize evenly. Keep the heat low and stir often until deep golden brown for the best flavor.
Butter, Flour, Milk, Chicken BrothWhisk the flour into the melted butter until smooth, then slowly add milk and broth while whisking to keep the sauce smooth and lump-free.
MacaroniChoose small pasta that cooks quickly and holds sauce well. Stir often while cooking so the pasta doesn’t stick to the bottom.
Gruyere, Mozzarella, ParmesanGrate the cheese yourself for a smooth, creamy sauce. Add one cheese at a time and stir gently until each melts completely.
Garlic Powder, Onion Powder, Salt, PepperTaste before serving and adjust as needed. A little extra seasoning at the end makes the flavor pop.

How To Make French Onion Mac and Cheese

  2. Make Roux: Melt butter, whisk in flour, and season.
  3. Build Sauce: Gradually whisk in milk and broth until smooth and thickened.

  5. Add Cheese & Onions: mix in cheeses until melted, then mix in onions and serve.

the cook’s Recipe Tip

My Top Tips!

  • Use a wide pan for onions: More surface area helps them caramelize faster and more evenly.
  • Don’t rush the onions: If they’re browning too fast, lower the heat and add a splash of water to loosen any bits stuck to the pan.
  • Add Cheese Slowly: mix in one handful at a time, letting each melt completely before adding more to keep the sauce smooth and lump-free.

Storage

Best enjoyed fresh off the stovetop. The pasta keeps absorbing liquid as it sits, so leftovers get thicker. Reheat gently on a low burner with a splash of milk to loosen the sauce.
