Sweet, golden, and irresistibly rich, these caramelized yellow onions are slowly cooked to perfection in butter until soft and jammy. Perfect as a topping for burgers, steaks, pizzas, or stirred into pastas and soups, they add a deep, savory-sweet flavor that transforms any dish.
Ingredients
- 3 large yellow onions (thinly sliced)
- 2 tbsp butter (or olive oil, or a mix)
- 1 tsp salt
Optional: 1 tsp sugar (helps speed caramelization)
Optional: splash of balsamic vinegar or wine (for extra depth)
Directions
- Prep: Slice onions into thin half-moons.
- Heat pan: Place a large skillet over medium-low heat. Add butter or oil.
- Cook onions: Add onions and salt. Stir to coat evenly.
- Slow & steady: Cook for 30–40 minutes, stirring every few minutes. Don’t rush—low heat brings out the natural sugars.
- Optional boost: If they look dry, add 1–2 tbsp water. For deeper flavor, add sugar, balsamic, or wine during the last 10 minutes.
- Finish: Onions should turn deep golden brown, soft, and jammy.
Uses: Burgers, steaks, pizzas, grilled cheese, pastas, or as a topping for roasted veggies.
