Low-Calorie Roasted Brussels Sprouts

Low-Calorie Roasted Brussels Sprouts

There’s something almost magical about what a hot oven does to a Brussels sprout. Cut them in half, toss them with a little oil, and roast until the edges turn crispy and brown, and you get something so good you’ll forget you’re eating a vegetable that’s basically zero guilt. This is the recipe I make on repeat when I want something easy, healthy, and actually craveable.

This one comes together with barely any effort. You’re looking at maybe five minutes of prep before the oven does the rest of the work for you.

The flavor is the real star here. Roasting brings out a natural sweetness in the sprouts while those crispy, caramelized edges add a little crunch that plain steamed or boiled sprouts just can’t touch.

It’s also light enough to eat a big plate of without any guilt. A serving comes in low on calories but high on fiber, so you actually feel satisfied instead of hungry an hour later.

Ingredients You’ll Need

You really only need a handful of things for this. Fresh Brussels sprouts are the obvious star, and you want to look for ones that are firm and bright green, without any yellowing leaves.

A little olive oil helps everything crisp up and carry flavor, but you don’t need much at all to get that golden, roasted look. Salt and pepper do most of the heavy lifting seasoning-wise, though I almost always throw in some garlic powder too because it adds so much without any extra calories.

If you want to change things up, a squeeze of lemon juice at the end brightens everything up nicely. Some people like a pinch of red pepper flakes for a little heat, or a sprinkle of grated parmesan right when they come out of the oven for a savory finish. All totally optional, but fun ways to keep this recipe from getting boring.

Tips for the Best Results

Cut your sprouts in half, not smaller. This gives you that flat surface that gets beautifully browned and crispy while the inside stays tender.

Don’t crowd the pan. Tip: spread the sprouts out in a single layer with a little space between each one, because if they’re packed too tight, they’ll steam instead of roast, and you’ll miss out on that crispy texture.

Roast them cut-side down for at least the first part of cooking. This is where all that gorgeous caramelization happens, and it makes a real difference in both flavor and looks.

High heat is your friend here. A hot oven, somewhere around 400 to 425 degrees, gives you that crispy exterior fast, before the inside has a chance to get mushy.

Storage and Reheating

Leftover roasted Brussels sprouts keep well in an airtight container in the fridge for about three to four days. They actually make a great addition to grain bowls or salads the next day if you don’t feel like reheating them at all.

When you do want them warm again, skip the microwave if you can. Note: reheating in the oven or air fryer at around 375 degrees for five to seven minutes brings back that crispy texture way better than a microwave ever will, which tends to leave them soft and a little sad.

If you’re meal prepping, you can roast a big batch at the start of the week and just reheat portions as you need them. They hold up surprisingly well and still taste great days later.

Frequently Asked Questions

Do I need to blanch Brussels sprouts before roasting?
Nope, not at all. Just wash them, trim the ends, cut them in half, and they’re ready to go straight into the oven.

Why are my roasted Brussels sprouts soggy instead of crispy?
This usually comes down to overcrowding the pan or not using high enough heat. Give them plenty of space and roast at a higher temperature for that crispy result.

Can I make this recipe with frozen Brussels sprouts?
You can, but the texture won’t be quite as crispy since frozen sprouts hold more moisture. If that’s what you have on hand, just pat them as dry as possible before roasting and expect a slightly softer result.

How many calories are in a serving of roasted Brussels sprouts?
A typical serving made with just oil, salt, and pepper usually lands around 80 to 100 calories, which makes this an easy, satisfying side dish to build a meal around.
