Ingredients:

  • 1 tablespoon olive oil
  • 1 tablespoon and ¼ cup of unsalted butter, separated.
  • 1 medium sweet onion, thinly sliced
  • 1½ cups thinly sliced button mushrooms
  • 2 cloves garlic, minced
  • ¼ cup balsamic vinegar
  • ¼ cup all-purpose flour
  • ½ cup half and half cream
  • 1½ cups milk
  • 1½ cups shredded cheddar cheese
  • ⅓ cup grated Parmesan cheese
  • 1 pound of elbow macaroni, prepared following the directions on the package.
  • Salt and pepper, to taste
  • Fresh minced parsley (optional, for topping)

Instructions:

  1. Caramelize the Onions:
    • In a large skillet, heat 1 tablespoon olive oil and 1 tablespoon butter over medium heat. Add the thinly sliced onions and cook, stirring occasionally, for 15-20 minutes until the onions are soft and caramelized.
    • Add the balsamic vinegar and cook for an additional 2-3 minutes, allowing the vinegar to reduce and coat the onions.
  2. Cook the Mushrooms:
    • In the same skillet, add the remaining ¼ cup butter and the sliced mushrooms.
    • Sauté for 5 to 7 minutes until the mushrooms are golden and soft.
    • Stir in the minced garlic and cook for another minute until fragrant. Set the mushroom mixture aside with the onions.
  3. Make the Cheese Sauce:
    • In the same skillet (no need to clean it), sprinkle the flour over the remaining butter and mushrooms to create a roux. Stir constantly for 1-2 minutes until the flour is slightly browned.
    • Gradually whisk in the half and half and milk, stirring until the mixture begins to thicken (about 5-7 minutes).
    • Reduce the heat to low and stir in the shredded cheddar cheese and grated Parmesan cheese until melted and smooth.
  4. Combine the Pasta and Sauce:
    • Stir the cooked elbow pasta into the cheese sauce until well coated.
    • Add the caramelized onions and mushrooms, gently folding them into the pasta.
  5. Serve:
    • Serve the mac ‘n’ cheese hot, topped with fresh minced parsley for a pop of color and freshness (optional).
