🥣 How to make (step-by-step photos)

1️⃣ Step One: Prep oven and veggies

First, preheat the oven to 400 degrees F (200 C). Wash and dry the vegetables.

  1. To cut asparagus: Line up your asparagus stalks on a cutting board. Cut off the bottom of the stalks where they are fibrous. If you’re not sure how much of the stalk to remove, simply bend it near the bottom and it will snap in just the right place! After removing the bottoms, cut the stalks into 1-2 inch pieces.
  2. To cut cauliflower: Remove the stem from the cauliflower head. Next, slice the head in half and cut away the florets.

👉 Pro tip! When prepping asparagus and cauliflower, cut them into similarly sized pieces. This will help them roast evenly and make them easier to eat.

2️⃣ Step Two: Season your veggies

Place prepared vegetables on a roasting pan or sheet pan.

Toss the cauliflower and asparagus pieces with olive oil until evenly coated. Sprinkle sliced garlic on top, and then season with salt and pepper.

👉 Pro tip! See the “Seasoning Ideas” section below for more ways to flavor this dish.

3️⃣ Step Three: Roast cauliflower and asparagus

Your last step is to roast the vegetables in the oven. Cook them for for about 25 minutes or until they begin to brown.

To help ensure even roasting, stir the asparagus and cauliflower halfway through cooking time.

Remove veggies from the oven. Serve immediately to use as a side dish, or let cool and serve as a topping for salads or bowls.

👉 Pro tip! The roasting time for your asparagus will depend on the size of the stalks. Thinner, shorter stalks may take as little as 15 minutes, and larger stalks will require around 25 minutes.

Recipe Q&A

How do I keep my veggies fresh before prep day?

There are simple ways to keep your veggies fresh between the time you purchase them and prep day or cooking day. Place your asparagus upright in a jar with water (like a bouquet of flowers!), and store in the fridge. Store your cauliflower in the fridge also, either in a loosely wrapped plastic bag or its original packaging. Be sure to allow air circulation and do not leave the wrapping completely sealed or too tight.

How do I get roasted asparagus and cauliflower to roast evenly?

As we mentioned, it’s helpful to cut the cauliflower and asparagus into evenly sized pieces to help them cook evenly. Also, separate the vegetables on the roasting pan. If your asparagus is cooking faster than the cauliflower florets, remove the asparagus to a plate and continue to cook the cauliflower.

💡 Seasoning ideas

This simple roasted vegetables recipe is delicious using just garlic, salt, and pepper. However you have plenty of options! Here are some more ideas for seasoning your baked asparagus and cauliflower:

  • Fresh lemon flavor: a bit of citrus zest and lemon juice will add a delicious twist to your vegetables
  • Add nuts: once they’re out of the oven, top your veggies with nuts, such as roasted sliced almonds
  • Parmesan cheese: freshly grated Parmesan cheese is a lovely complement to the veggies in this recipe. Try nutritional yeast if you want cheesy flavor in a dairy-free dish

🧊 How to store leftovers

  1. Refrigerator storage: Store leftovers in an airtight container in the fridge for up to 3-4 days.
  2. Freezer storage: For best flavor and texture, do not freeze and reheat your roasted vegetables.
