- Harissa- Sprinkle on harissa seasoning in place of the pepper for a spicy kick.
- Cajun- Replace the oil with Cajun butter.
- Spicy Southwest- Sprinkle on a mixture of 1 teaspoon each of chili powder, cumin, and garlic powder plus a healthy pinch of crushed red pepper flakes.
- Soy-Glazed- Replace the EVOO with a mixture of 1 tablespoon tamari (gluten-free soy sauce), 1 teaspoon honey, and 1 teaspoon sesame oil.
- Parmesan and Herb- Sprinkle on 1 tablespoon of minced herbs (I like thyme and rosemary) and top with freshly grated parmesan cheese as soon as the mushroom caps are removed from the oven.

- Spread out the mushrooms on the baking sheet and lightly oil both sides. Sprinkle with salt and black pepper.
- Roast in a 400 F degree oven for 15 to 20 minutes. Flip halfway through for even caramelization. Slice the mushrooms into ½ inch slices, if desired, and serve or use in your recipe.
👩🏻🍳 Expert Tip
Space the mushrooms apart to ensure they roast rather than steam.
🥗How to Served Roasted Mushrooms
A few ways to use mushrooms include serving with roasted zucchini and roasted eggplant then top with romesco sauce, feta (optional), toasted pine nuts, and fresh parsley for a complete meal.
For a quick and easy dinner toss with pasta and San Marzano tomato sauce.
Serve with my almond flour chicken piccata or gluten-free alfredo.
These mushrooms have a meaty texture so you can also use them as the star of the show.
Try serving them sliced as a main course, just as you would a steak with chimichurri or dairy-free pesto.

Frequently Asked Questions
How to Store Fresh portobello Mushrooms
portobello mushrooms kept in the refrigerator should be used within a week. Remove mushrooms from any plastic wrapping, which can trap moisture.
Instead, place fresh portobello mushrooms in paper bags or wrap them in a paper towel and place in an open plastic bag for storage in the refrigerator.
How to Clean Mushrooms
I place the mushrooms in a colander and rinse with cool water. Then use a clean towel to dry and rub off any remaining dirt.
