Ingredients You’ll Need
These ingredients each play an important role in creating the savory, herby flavor and perfect texture:
Fresh Brussels Sprouts: Packed with fiber and nutrients, Brussels sprouts become sweet and slightly crispy when roasted. Be sure to halve them so they cook evenly.
Baby Bella Mushrooms: These mushrooms add a deep, earthy flavor that pairs perfectly with Brussels sprouts. Their natural moisture keeps them tender when roasted.
Avocado Oil: With a high smoke point, avocado oil is ideal for roasting. It helps achieve a nice, even roast without any burnt flavors.
Salt & Pepper: Adds essential seasoning and enhances the natural flavors of the veggies.
Garlic Powder (1 tbsp): Garlic powder brings out a warm, aromatic flavor that perfectly complements the Brussels sprouts and mushrooms.
Onion Powder (1 tbsp): This gives a mild sweetness and extra layer of flavor to the vegetables.
Oregano (1 tbsp): This classic herb has a slightly peppery, woody taste that balances the dish.
Thyme (1 tbsp): Thyme adds an earthy, floral note, making the dish aromatic and warming.

Tips for the Best Roasted Brussels Sprouts and Mushrooms
Cut Brussels Sprouts Evenly: Halving the Brussels sprouts ensures they roast evenly and get that crispy edge.
Spread Out on Baking Sheet: Avoid overcrowding to allow even roasting. If needed, use two baking sheets for a perfect roast.
Roast Until Golden: For the best flavor, cook until golden brown, checking around 15 minutes to prevent burning.
Frequently Asked Questions
Can I use olive oil instead of avocado oil?
Yes, olive oil works well too, but avocado oil’s high smoke point makes it ideal for roasting at higher temperatures.
How can I add extra flavor to this dish?
For a little extra flavor, try adding a sprinkle of parmesan cheese or a squeeze of lemon juice just before serving.
What’s the best way to store leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven to maintain crispiness.
