Cooking Instructions

Follow these simple steps to prepare this delicious Balsamic Caramelized Onion Mac ‘n’ Cheese:

Step 1: Boil the Pasta

Start by bringing a large pot of salted water to a boil over high heat. Add in the elbow macaroni and cook until al dente according to package instructions (usually about seven minutes). Drain and set aside.

Step 2: Sauté the Onions

In a large skillet over medium heat, melt two tablespoons of butter. Slice the onions thinly and add them to the skillet. Stir occasionally while they cook down until they turn golden brown and sweetly fragrant—about twenty minutes.

Step 3: Make the Sauce

In another pot, melt the remaining butter over medium heat. Whisk in flour until smooth (about one minute), then gradually pour in the milk while continuing to whisk until thickened (about five minutes). Stir in shredded cheddar until melted.

Step 4: Add Flavor

Pour in balsamic vinegar over the caramelized onions and stir well for about two minutes. Mix this flavorful onion concoction into your cheese sauce along with cooked macaroni.

Step 5: Combine & Bake

Transfer everything into a greased baking dish and mix well. If you’re feeling fancy, sprinkle some extra cheese on top! Bake at 350°F (175°C) for twenty-five minutes until bubbly and golden on top.

Step 6: Serve & Enjoy

Scoop generous portions onto plates or into bowls. A sprinkle of fresh herbs or cracked black pepper can elevate it even further!
