🥦 How to make (step-by-step photos)
1️⃣ Step One: Prep oven and vegetables
First, preheat your oven to 400 degrees F (200 C), then prep the vegetables with a quick wash before cutting them.
- To cut onions: Cut stems from the onion and then make a slice around the outside to remove the outer layer. Cut the onion into rounds, or in half and then into slices.
- To cut broccoli: Remove the broccoli florets from the stalk, and if desired, slice florets into smaller pieces.
👉 Cutting tip: Cut roasted vegetables like broccoli and onions into similarly sized pieces so they’re easier to eat, have similar cooking times, and get an extra crunch.
2️⃣ Step Two: Season and add to baking sheet
Next, place the cut broccoli and onions on a roasting or sheet pan.
Toss the veggies with olive oil until completely coated. Season with sliced garlic, as well as salt and pepper to taste.
👉 Roasting tip: Keep the vegetables separated on the roasting pan. Broccoli can a bit take longer to bake. If needed, you can easily scoop the roasted onions off the pan when they’re done and keep cooking the broccoli.
3️⃣ Step Three: Bake vegetables in the oven
Now you’ll roast the vegetables in the oven until they begin to brown, which takes about 25 minutes depending on your oven.
To make sure the onions and broccoli cook evenly, stir the vegetables halfway throughout cooking. If the onions are cooking faster, remove them to a plate and continue to cook the broccoli until it’s done.
When the veggies are done cooking, take them out of the oven. If using as a side dish, serve them immediately. You can also let them cool and serve on top of salads or bowls.
💡 Seasoning ideas
We kept it simple with garlic, salt, and pepper in this recipe, but here are some more seasoning ideas:
- Add citrus: a bit of squeezed lemon or lime over the top of these vegetables will add a fresh, acidic kick
- Add cheesy flavor: shaved parmesan or nutritional yeast will make this dish more robust
- Add some heat: paprika, chili powder, and a little cayenne will spice it up
