As a mushroom fan, whether I’m cooking at home or eating at a restaurant, my go-to toppings for both steaks and burgers are delicious sauteed mushrooms and onions.

It’s such a great way to amp up the flavor of a main dish or to try a new savory side dish.

While these cooked mushrooms and onions are packed full of flavor, they’re actually rather quick and easy to prepare.

🥘 Ingredients

  • 3 tablespoons butter – if you use salted butter be careful with your seasoning. You can also use an oil like olive oil, but butter adds the best flavor.
  • 10 ounces sliced mushrooms – My favorite type of mushroom to use for these sauteed mushrooms are baby bella mushrooms, but regular white mushrooms is also tasty just a bit less intense mushroom flavor
  • 1 large onion peeled and sliced into half-moons – I typically use yellow onions or sweet onions
  • 2 tablespoons Worcestershire sauce – See variations for substitute ingredient ideas
  • 3 cloves garlic, minced – Can also use garlic powder
  • Salt, to taste
  • Ground black pepper, to taste
  • Optional: ¼ teaspoon mushroom powder – this will amp up the mushroom flavor even more
  • Optional: 1 ½ teaspoon fresh herbs – such as thyme, rosemary, or parsley (½ teaspoon if dried)

🍳 Equipment

📙Instructions

  1. Heat butter in a large skillet over medium high heat, being careful that it doesn’t burn. Add the mushrooms and cook until they start browning, stirring every minute or so.
  2. Add more butter and the sliced onion. Continue cooking until is translucent and slightly browned, about 5 minutes. Continue stirring every minute or so.
  3. Reduce the heat to low, add the rest of the butter, Worcestershire sauce, and garlic. Cook for one minute, stirring continuously. Season to taste with salt and pepper (and mushroom powder and herbs, if desired). Serve immediately.

If you happen to have leftovers, store them in the fridge in an airtight container and add to your eggs in the morning or some pasta for a quick lunch.

♻️ Variations

Instead of using worcestershire sauce I sometimes like to use balsamic vinegar. I’ve found that the flavor and intensity can vary among brands, so I suggest starting with a tablespoon and then adjust to your taste.

You could also use soy sauce, just be aware of the extra salty flavor before adding salt or using salted butter.

Want to add a bit of fresh acidic flavor? Add a squeeze of fresh lemon juice just before serving.

🍽 Make It A Meal

Sauteed onions and mushrooms make for an easy side dish to many meals (like this Roasted Pork Tenderloin) or make a dish even better by adding flavor as a topper or mix in. Some ideas include:

A topping for burgers, steak, grilled pork chops, fried or oven-roasted potatoes, pasta, or your favorite breakfast skillet.

I also love using it as a filling in an omelet or stirring into cheesy scrambled eggs.
