These Carbs Don't Count
June 7, 2025
This Caramelized Onion Mac & Cheese is ultra-indulgent and packed with layers of flavor. Sweet, deeply golden onions are slow-cooked to perfection and stirred into a creamy sauce made with heavy cream, butter, and a blend of cheddar and mozzarella. Tossed with tender shell pasta and finished with a final cheesy flourish, this dish is the perfect cozy comfort food with a gourmet twist.
