Oven Roasted Mushrooms  | Julie Blanner

Easy Roasted Mushrooms make a wholesome, delicious appetizer or side dish. These garlic mushrooms take just five minutes, hands-on time!

Roasting mushrooms in the oven keeps them low-calorie, low-carb, Whole30, and keto-approved. This recipe works with white, button, or cremini mushrooms.

I recently hosted a woodland themed baby shower for my niece and served these amazing garlic mushrooms. At the last minute I decided I needed another savory gluten free, dairy free appetizer, but was short on time.

Fortunately, this oven roasted mushrooms recipe is effortless and even fits the theme! Who doesn’t love mushrooms? (Well, I am sure some people don’t, but when they are this good, I bet we can convince those people to enjoy them too!)

These garlic mushrooms are light and healthy, but taste rich and hearty! They’re so filling, yet with flavor this good, you just can’t get enough of them. They’re perfectly poppable, but are also amazing tossed in just about everything.

Roasted mushrooms are one of the quickest and easiest side dishes. You can marinate them in a plastic bag with oil, garlic and herbs or in the dish you bake them in. In less than 5 minutes they’re oven ready!

Oven roasted mushrooms require less oil than you need to sauté them on the stove. When you roast mushrooms in a single layer in the oven, they bake in their natural juices creating a tasty sauce.

This process makes them incredibly tender. When you remove them from the oven, just drizzle the pan juices over the roasted mushrooms to make them even more amazing!

You can roast more than just mushrooms – try my roast chicken, roasted baby carrots, or cauliflower for another flavorful side option.

Garlic mushrooms have so much flavor – with so little effort. They make a delicious savory appetizer or side dish. They turn out golden brown and SO savory, you won’t be able to keep your hands off them!

Why You’ll Love This Recipe

Wholesome—White Mushrooms are packed full of nutrients. They’re a great source of fiber, Vitamin D, Vitamin B, and potassium! Mushrooms are also low-carb and work with Whole 30 and Keto lifestyles.

Minimal Ingredients – You only need a handful of ingredients to make this garlic mushroom recipe.

Easy to Customize – I use one of my favorite seasoning blends in this recipe (it’s the same blend I use in my bread dipping spices). However, you can easily adapt this mushroom recipe with your favorite spices using garlic and olive oil. It’s fun to mix it up when you make them over and over again!

Ingredients and Substitutions

• White Mushrooms – Button mushrooms are delicious, too.
• Minced Garlic – I always use minced garlic from a jar found in the produce section but you can freshly mince garlic if you prefer. Learn how to mince garlic here.
• Olive Oil – You can use any type of oil that can withstand high heat.
• Balsamic Vinegar – For an acidic bite of flavor.
• Herb Blend – Use your favorite dried herbs here. Fresh thyme, rosemary, or oregano are classic pairings. We’re sharing our best blend in the printable recipe card below.

Variations

• If you want a sweeter flavor profile, use this balsamic glaze (after roasting them) instead of the traditional balsamic vinegar in the marinade.
• Try them with a touch of cream for a delicious twist, or blend them into butter.

How to Roast Mushrooms

1. Preheat oven. Clean mushrooms (notes below). Mix olive oil and herbs together in a bowl.
2. Drizzle or toss white mushrooms with extra virgin olive oil, balsamic minced garlic and herbs.
3. Spread them in a single layer in your casserole dish or sheet pan. Cook mushrooms as directed (cooking time will depend on the moisture content of your mushrooms), until tender.
4. Drizzle the pan juices over the mushrooms and serve!

How to Clean White Mushrooms

• In cold water, rinse off each mushroom under the faucet individually, removing any dirty spots by rubbing your fingers over them.
• You can clean them with a damp paper towel if you prefer. Place on paper towels to absorb any extra water.
• Mushrooms absorb water so take a less is more approach to cleaning them.
• For the perfect roast, cook them immediately after cleaning.

Tips From My Test Kitchen

• We like to combine the clean mushrooms, olive oil and herbs in a ziplock bag to ensure all the mushrooms are covered, like a marinade.
• Did you know that you can freeze mushrooms? These mushrooms freeze fabulously. It is simple to toss in the freezer and reheat when you want a rich and comforting accompaniment. Read more in the “how to store” section below.

Serving Suggestions

• You’ll want to serve them with just about everything.
• They pair well with steak, Baked Chicken Breast, burgers and so much more!
• You can even serve garlic mushrooms on toast or crostini!
• Enjoy roasted mushrooms tossed in dishes like pasta, chicken, steak, casseroles, pizzas, soups, stews and more!

How to Store

• Room Temperature– Roasted mushrooms can sit out at room temperature for up to two hours safely, while serving.
• Refrigerator – Roasted mushrooms will keep for 3-4 days in the refrigerator.

• Freezer – You can store oven roasted mushrooms in an airtight container for up to three months in a freezer. Allow them to cool to room temperature before freezing. Place mushrooms in a freezer bag in a single layer and store horizontally. Since mushrooms have high water content, it’s best to prepare them (like roasting them) before freezing. This will give them a lot more versatility in how you use them!
