How to Make Balsamic Caramelized Onion Mushroom Mac & Cheese
Follow these simple steps to prepare this delicious dish:
Step 1: Prepare the Pasta
Cook your elbow macaroni according to package instructions until al dente. Drain and set aside while you work on those heavenly toppings.
Step 2: Caramelize the Onions
In a large skillet over medium heat, melt two tablespoons of butter. Add thinly sliced onions and cook them low and slow for about 20 minutes until they turn golden brown and sweetly fragrant. Stir occasionally—don’t leave them hanging!
Step 3: Sauté the Mushrooms
Add one cup of sliced mushrooms to your skillet with the caramelized onions and another tablespoon of butter. Cook until they’re tender—about five minutes—and season with salt and pepper.
Step 4: Make the Cheese Sauce
In a separate saucepan, melt three tablespoons of butter over medium heat. Whisk in flour until combined; gradually add two cups of milk while continuing to whisk until smooth. Stir in cheddar cheese until melted, then mix in mozzarella.
Step 5: Combine Everything
Once your cheese sauce is ready, fold in cooked macaroni along with balsamic vinegar into your skillet filled with onions and mushrooms. Mix well—this is where flavor magic happens!
