Balsamic Mushrooms and Onions
Description
This recipe highlights the natural earthy flavor of white button mushrooms complemented by softened onions cooked in olive oil. Initially cooked covered to release and then evaporate the mushrooms’ liquid, the vegetables develop a rich, concentrated flavor. The final step of stirring in balsamic vinegar enhances the dish with a pleasant acidity and glossy finish.
The mushroom halves and thin onion slices create a mix of textures, where tender mushroom and slightly caramelized onion coexist. The seasoning is simple, relying chiefly on salt and the vinegar’s complexity.
Served as a side, this dish complements proteins or can be integrated into sandwiches or atop toasts. The mushrooms and onions can be stored for several days chilled, with flavors developing over time, making leftovers practical.
Choosing white button mushrooms ensures a mild, family-friendly flavor, while thin slicing the onion balances its sharpness. Substituting shallots offers a more subtle onion note.
Ingredients
- 2 tablespoons olive oil
- 2 pounds white button mushrooms halved (see note 1)
- 1/2 medium onion peeled and thinly sliced (about 5 ounces, see note 2)
- salt
- 2 tablespoons balsamic vinegar
Instructions
- In a medium skillet over medium-high heat, heat oil until shimmering. Add mushrooms, onions, and 1/4 teaspoon salt and stir to combine.
- Reduce heat to medium, cover, and cook until liquid is released from mushrooms, about 5 minutes. Remove cover and continue to cook until liquid has evaporated and mushrooms and onions are softened and browned, about 5 minutes longer.
- Stir in balsamic vinegar and stir until mushrooms and onions are coated evenly and the vinegar is heated through, about 2 minutes.
Notes
- White button mushrooms provide mild, family-friendly umami; alternatives can be used based on preference.
- Use half a medium onion, thinly sliced, roughly 1 cup loosely packed.
- Shallots can replace onion for a milder flavor.
- Recipe yields about 2 cups, enough for four half-cup servings.
- Store leftovers refrigerated and covered for up to 4 days.
