🥣 How to make (step-by-step photos)
1️⃣ Step One: Preheat oven + prep vegetables
First, preheat your oven to 400 degrees F (200 C), then get the brussels sprouts and cauliflower ready with a quick wash before cutting them.
To cut brussels sprouts: Remove the stems, then cut the sprouts in half or in quarters. We like to cut large brussels sprouts into smaller pieces for extra crisp when baked.
To cut cauliflower: Cut the stem and leaves from cauliflower, then cut the florets from the head into 1-inch pieces for roasting.
2️⃣ Step Two: Add vegetables to a sheet pan
Once the brussels sprouts and cauliflower are cut, place them on a roasting or sheet pan.
Pour a small amount of olive oil over the vegetables and toss with your hands or a spatula until the oil covers them completely.
Sprinkle sliced garlic, salt, and pepper over the vegetables.
3️⃣ Step Three: Roast vegetables until golden brown
Place the sheet pan in the oven and roast for about 35 minutes until brussels sprouts and cauliflower are tender and browned around the edges.
Halfway through roasting, stir the vegetables to make sure they brown on all sides. We did this when they were about 20 minutes into cooking.
When done, remove the veggies from the oven. If using as a side dish, you can serve them immediately. You can also let them cool and combine with salads and bowls.
❓ Recipe questions + quick tips
Moist heat cooking methods, like steaming and boiling, can make brussels sprouts mushy. Roasting them typically solves this problem, but they can become mushy if you add too much oil. Make sure to drizzle just a small amount of olive oil over the brussels sprouts before you roast them, and they should come out crispy and delicious (not mushy!).
Brussels sprouts should be cut before roasting. Cutting brussels sprouts in half or in quarters before cooking makes them crispier when baked. Cut brussels sprouts cook more quickly and take on richer flavor, and lose their natural bitterness when in high heat.
It is a good idea to wash cauliflower before roasting it to remove dirt and germs. We recommend rinsing it off before cutting it into florets. Once you wash cauliflower, it spoils more quickly, so you should use it right away.
We don’t suggest freezing baked cauliflower. The freezing process reduces its flavor and it could become mushy when reheated. Instead of freezing baked cauliflower, you can store it in the refrigerator for 3-4 days and add to other meals.
🌱 Herb + spice combination flavor ideas
Garlic, salt, and pepper is all you need to make this dish burst with flavor. However, you can get creative with herbs and spices for a different take on this foundational dish.
- Rosemary, shallots, and garlic: roasted brussels sprouts and cauliflower taste delicious when combined with thinly sliced shallots and garlic, and a sprinkle of rosemary on top.
- Paprika, onion powder, chili powder, and cumin: add a spicy kick to roasted vegetables with a sprinkle of paprika, onion powder, chili powder and a dash of cumin.
- Parsley, thyme, and tarragon: roast vegetables with some parsley, thyme, and tarragon for a savory flavor.
- Fresh lemon juice: Squeeze a little lemon juice on top of roasted brussels sprouts and cauliflower for a bit of a sweet (and sour!) taste.
- Nutritional yeast: A cheesy-like seasoning that adds a unique savory flavor to vegetables. Your new favorite vegan topping!
🧊 How to store
Roasted brussels sprouts and cauliflower are so delicious, you’ll want to eat it all right away! If you have some left over, you can save the veggies until ready to serve. Here’s how to store for the best flavor:
- Refrigerator storage: Roasted vegetables should be stored in an airtight container in the refrigerator for up to 3-4 days.
- Freezer storage: For the best taste and texture, we don’t recommend freezing.
