I just love these sweet onions! I put them on grilled Portobello mushrooms, hamburgers, steaks, omelets and on grilled vegetable sandwiches.
- In a large skillet, melt the butter over medium-high heat.
- Add the onions and reduce the heat to medium-low.
- Cook slowly, stirring occasionally, until golden brown and caramelized, about 30 minutes.
- Add the thyme, rosemary, salt and pepper, and brown sugar; stir well to combine.
- Cook for 5 more minutes.
