Roasted Brussels Sprouts and Asparagus
This side dish combines two of the best vegetables! It’s similar to our Roasted Potatoes and Broccoli only this recipe uses asparagus and brussels sprouts. When properly seasoned and roasted these veggies have a ton of flavor.
Our recipe uses a little avocado oil, garlic powder, onion powder, salt, and pepper. With only about 10 minutes of prep and 25 minutes of cook time, it doesn't get much easier than that!
Ingredients and Possible Substitutions:
- Brussels Sprouts: Choose fresh brussels sprouts for this recipe. Frozen (thawed) don't yield the same results.
- Asparagus: Similar to the brussels sprouts, fresh asparagus is the way to go.
- Oil: We use avocado oil because of its mild flavor and high smoke point. Choose another high smoke point cooking oil similar to canola, vegetable, etc. if you'd prefer not to use avocado oil.
- Seasonings: Garlic powder, onion powder, salt, and pepper. Adjust or omit any of these seasonings to fit your tastes.
How to Roast Asparagus and Brussels Sprouts:
These roasted veggies use minimal ingredients and yield big results. Plus, they take very little time to prepare.
See the recipe card below for the ingredient amounts and full instructions.
- Preheat your oven to 425ºF, and line a large sheet pan with aluminum foil or parchment paper. (See the tip below about roasting without the use of foil or parchment paper.)
- Separate the asparagus and brussels sprouts between two mixing bowls.
- Divide the oil and seasonings between the two bowls.
- Toss the asparagus until it's well coated with oil and seasonings. Then toss the brussels sprouts until entirely coated.
- Pour the brussels sprouts onto the baking sheet in an even layer. Roast for 10 to 15 minutes then remove the pan from the oven.
- Carefully add the asparagus to the pan, and continue roasting for an additional 10 minutes or until the veggies reach the desired consistency.
- Serve warm with your favorite entree!
Tips for Success:
- The cook time may vary depending on how, “done,” you like your vegetables.
- While using foil or parchment paper makes cleanup easy, I've found that spraying the baking sheet with cooking spray gives the vegetables better caramelization.
- Add smoked paprika, thyme, Parmesan cheese, breadcrumbs, balsamic vinegar, sliced almonds, chopped walnuts, or crumbled bacon for extra flavor.
- Cut large brussels sprouts into fourths and small brussels sprouts in half for even cooking.
- Roasted asparagus and brussels sprouts are best served immediately for the best flavor and texture.
Storage and Reheating Options:
Refrigerator: Store any leftover roasted vegetables in the refrigerator for up to 2 days.
Reheating: Reheat in a skillet on the stovetop over low heat or in the oven or toaster oven at 350°F until heated through.
Should You Parboil Brussels Sprouts Before Roasting?
No, you should not parboil brussels sprouts before roasting as it can cause the outer leaves to become soggy. Roasting them on a lightly oiled pan without parboiling yields the best results, allowing the vegetables to caramelize and develop a slightly sweet, nutty flavor from being roasted in the oven.
Why Are My Roasted Brussels Sprouts Not Crispy?
Roasted brussels sprouts may not be crispy due to a few reasons. To ensure the brussels sprouts are properly roasted and crispy, preheat your oven to 425°F and spread them out in an even layer on a baking sheet (cooking spray gets them crispy better than using foil or parchment paper).
Make sure the brussels sprouts are well-dried; otherwise, they'll steam and become soft rather than roast. We like to use a salad spinner to spin the water out after rinsing.
Should You Soak Brussels Sprouts Before Roasting?
Nope, not for this asparagus and brussels sprouts recipe. Soaking causes the brussels sprouts to absorb extra water and they're more likely to steam instead of roast.
