I wasn't always a fan of mac and cheese, to be honest. It wasn't until I tried a version with caramelized onions at a small bistro in upstate New York that my mind was changed forever. The sweetness of the onions, the saltiness of the bacon, combined with that rich, cheesy sauce... it was an epiphany! I had to recreate it. It took a few tries to get it just right, but believe me, the effort was worth it. Now, it's a staple in my house, and I'm excited to share it with you.

🍽 Ingredients

📖 Instructions

  1. First things first, let's get those onions going. Slice two large yellow onions thinly. It's okay if you shed a tear or two; it just means you're putting love into the dish. Heat 2 tablespoons of olive oil in a large skillet over medium-low heat. Add the sliced onions, sprinkle with a pinch of salt and a teaspoon of sugar, and cook, stirring occasionally, for about 30-40 minutes, or until they're a deep golden brown and beautifully caramelized. This step is crucial; don't rush it!
  2. While the onions are doing their thing, cook 8 ounces of bacon in the same skillet (or a separate one, if you prefer). Cook until crispy, then remove and drain on paper towels. Once cooled, crumble the bacon into bite-sized pieces. Reserve about 2 tablespoons of bacon grease; it'll add amazing flavor to the cheese sauce.
  3. Preheat your oven to 375°F (190°C). Now, let’s cook the pasta. Bring a large pot of salted water to a boil. Add 1 pound of elbow macaroni (or your favorite pasta shape; cavatappi and shells work great too) and cook according to package directions, until al dente. Drain the pasta well and set aside.
  4. Time for the cheese sauce. In the same large pot you used for the pasta, melt 4 tablespoons of butter over medium heat. Whisk in 4 tablespoons of all-purpose flour and cook for 1-2 minutes, stirring constantly, to create a roux. Gradually whisk in 3 cups of whole milk until the mixture is smooth and there are no lumps. Continue whisking until the sauce thickens slightly, about 5-7 minutes.
  5. Remove the pot from the heat and stir in 4 cups of shredded cheese. I like to use a mix of cheddar, Gruyere, and Monterey Jack, but feel free to experiment. Stir until the cheese is completely melted and the sauce is smooth and creamy. Add the reserved bacon grease, a teaspoon of Dijon mustard, and a dash of hot sauce (if you like a little kick). Season with salt and pepper to taste.
  6. Add the cooked pasta to the cheese sauce and stir to combine. Fold in the caramelized onions and most of the crumbled bacon, reserving some for topping. Pour the mac and cheese into a greased 9x13 inch baking dish.
  7. Sprinkle the remaining crumbled bacon over the top of the mac and cheese. Bake in the preheated oven for 20-25 minutes, or until bubbly and golden brown on top. Let it stand for a few minutes before serving. Garnish with a sprinkle of fresh parsley, if desired. Enjoy your incredibly delicious Mac & Cheese with Caramelized Onions and Bacon!
