Heat up a skillet with the butter. Wait for it to melt.
2 Tablespoon Butter
Add in your sliced onions. Sauté the onions translucent.
1 Onion
Stir in all the sliced portobello mushrooms. Cook them so that they reduce and sauté gently.
9 Ounces Portobello Mushrooms
Season with ground pepper, salt and chopped or pressed garlic.
¼ Teaspoon Black Pepper Ground, ½ Teaspoon Salt, 2 Garlic Cloves
Once the mushrooms have reduced in size, pour in the white wine and keep on high to medium heat. Stir, cook for 1–2 minutes.
⅓ Cup White Wine
Add the Thyme and reduce further on slow heat until all the liquid is gone.
A Few Sprigs Thyme Fresh
Serve hot as a side dish with beef steak, roasted chicken, turkey, pork chops, poached salmon or vegetarian meatless meals. See the suggestions in the post.

Notes
You can use dried thyme too or omit it altogether; however, fresh thyme really adds value and flavor to the portobello mushrooms.
