What types of mushrooms do you recommend?

I like to use a variety of my favorite mushrooms, including shiitake, oyster, and sliced king trumpet mushrooms. Don’t worry: this dish still tastes great if you use only regular old white and brown button mushrooms. Just note that if you’re using a delicate mushroom (e.g. enoki or brown clamshell mushrooms), make sure you carefully coat them in the marinade and try not to break them up by accident. I normally add the sturdier mushroom varieties to the marinade first, and then add the more delicate ones at the end.

How do I cut the mushrooms?

Make sure you cut the mushrooms into roughly similar sizes so they finish cooking at the same time. I normally quarter large button mushrooms and adjust the size of the other mushrooms accordingly.

Can I use another vegetable in place of mushrooms?

If you have a mushroom allergy or you don’t quite have a pound of mushrooms, you can add some broccoli or cauliflower florets to the marinade and toss them on the sheet pan. And if you absolutely hate mushrooms…you might want to make some other recipe, ’cause this one’s all about the mushrooms!

Would chicken breast work in this recipe?

Yes! Just make sure that you you don’t overcook them—check that the thickest part of the chicken breast reaches between 150°F and 160°F and you’re good to go.

Ingredients

  • Shallot: I love using shallot in this recipe, but feel free to substitute onion or leeks.
  • Sherry vinegar or balsamic vinegar: Feel free to use lemon juice if you don’t have any vinegar in your pantry.
  • Coconut aminos
  • Red Boat fish sauce
  • Magic Mushroom Powder or Diamond Crystal kosher salt (if using fine grain salt or Morton’s kosher salt, use ½ teaspoon)
  • Boneless skinless chicken thighs 
  • Assorted mushrooms, cut into the same size pieces
  • Minced fresh Italian parsley and/or chives

How to make sheet pan chicken and mushrooms

Heat oven to 450°F or 425°F convection with the rack in the upper middle. As the oven heats up, combine the shallots, vinegar, extra virgin olive oil, coconut aminos, fish sauce, and Magic Mushroom Powder (or salt) in a large bowl.

Making the marinade for Sheet Pan Chicken and Mushrooms by adding Magic Mushroom Powder and sliced shallots to the liquid ingredients.

Stir well and then add the chicken to the marinade. 

Add chicken thighs to the marinade and coat well.

Shake off the excess marinade and transfer the chicken to a rimmed baking sheet. (Leave the marinade in the bowl, because you’re going to dump the mushrooms in next!)

Place the chicken thighs on a rimmed baking sheet in a single layer.

If you have a combination of different mushrooms, add the sturdier mushrooms (e.g. sliced King Trumpet, button, shiitake, etc.) to the marinade first and toss well…

Toss in the sliced mushrooms into the marinade left in the bowl.

…and then transfer them to the rimmed sheet in a single layer.

Arrange the mushrooms around the chicken thighs in a single layer.

Using delicate mushrooms (e.g. enoki or brown clamshell mushrooms)? Toss them carefully in the marinade after you’ve removed the sturdier ones so they don’t break apart.

Carefully toss in delicate mushrooms into the marinade so you don't break them apart.

Arrange the chicken, mushrooms, and shallots in a single layer on the sheet pan.

The Sheet Pan Chicken and Mushrooms should be arranged in a single layer before baking.

Pop the sheet pan dinner in the oven and roast for 25 to 35 minutes, rotating the tray 180° at the halfway point. 

Pop the tray of Sheet Pan Chicken and Mushrooms into a hot oven.

The dish should be done when the chicken is cooked through (a meat thermometer should read 165°F in the thickest part of the thigh or 150°F if you’re using chicken breasts) and the liquid from the mushrooms has mostly cooked off.

A steaming pan of chicken and mushrooms is being rotated at the halfway point.

Sprinkle on fresh herbs…

What do you serve with this sheet pan dinner?

I like to make a big green salad, stir-fry some vegetables, heat up some cauliflower rice, or pressure cook a batch of Instant Pot Kale and Carrots. Pick a vegetable side dish that’s quick and easy enough to be finished by the time the chicken and mushrooms are ready.
