🍆 Ingredients

For this roasted eggplant and cauliflower recipe, you need just 5 ingredients, plus a few kitchen tools that you probably already have on hand:

  • Eggplant: one large eggplant (any variety), which is about 1 pound
  • Cauliflower: you’ll need 1 head of cauliflower
  • Garlic cloves: cut fresh cloves into thin slices
  • Olive oil: start with 2 tablespoons and add more if needed, as eggplant will quickly soak up the oil

🥣 Recipe instructions (with step-by-step photos)

1️⃣ Step One: Prep oven and veggies

Preheat your oven to 400 degrees F (200 C). Wash and then dry the vegetables.

  1. To cut eggplant: Cut off the stem and the bottom of the eggplant. Cut one-inch slices lengthwise, then stack the slices together and dice into cubes.
  2. To cut cauliflower: Cut off the hard stem from the cauliflower. Next, slice in half, then cut away the florets.

👉 Pro tip! When prepping your cauliflower and eggplant, cut the pieces into similar sizes. This helps make them cook evenly and also makes them easier to eat.

Recipe questions + quick tips

Do I need to salt and drain the eggplant before roasting?

Traditionally, salting and draining eggplant was done to reduce the vegetable’s bitterness. However, the eggplants that are widely grown and purchased today are not bitter enough to require this step. Skip this step and save unnecessary time and effort!

How can I reduce prep time?

To minimize prep on cooking day, wash and cut the vegetables in advance. If you’re using eggplant and cauliflower as a topping for salads or bowls, bake the vegetables up to three days ahead of time.

How can I get my vegetables to roast evenly?

Cut the cauliflower and eggplant into same-sized pieces to help them roast evenly. Also, separate the vegetables on the pan rather than mixing them together. The cauliflower may roast more quickly than the eggplant. If so, remove cauliflower to a plate and continue to cook the eggplant.


💡 Ideas for seasoning

You can keep this recipe simple by using just garlic, salt, and pepper. For more variety, try some of these ideas:

  • Fresh or dried herbs: Try basil or Italian seasoning on your veggies.
  • Ginger or turmeric: These spices offer maximum flavor and a punch of color.
  • Parmesan cheese: Freshly grated Parmesan cheese will complement the garlic and veggies in this recipe. For a non-dairy option, try nutritional yeast or vegan Parmesan .

🧊 How to store leftovers

  1. Refrigerator storage: Store leftovers in an airtight container in the fridge. They will keep for up to 3-4 days. Reheat in the microwave or in a pan over medium heat on the stove.
  2. Freezer storage: To guarantee the best flavor and texture, do not freeze and reheat the vegetables after roasting as they will become mushy.
