It was one of those Thursday evenings when the world felt like it was spinning a bit faster than usual. I had finally wrangled the kids to bed, and there I was staring at a fridge that seemed emptier by the minute. But from somewhere in the depths of that fridge, a bag of Brussels sprouts peeked back at me. Paired with some pancetta I had tucked away (a gift from my last “I’m going to learn charcuterie” phase), I realized a deliciously satisfying dinner was just a roast away. These Roasted Brussels Sprouts with Red Onions and Pancetta are the perfect way to coax out the caramelized sweetness of Brussels sprouts, make your kitchen smell heavenly, and use up those random pantry ingredients. Honestly, it’s a little bit of magic in under an hour.

What You’ll Need

This dish is as much about what’s not in it as what is. Simple, fresh ingredients that you probably have hiding in your kitchen already.

• 1 lb of **Brussels sprouts**, halved
• 3-5 cloves of **garlic**, pressed
• 1/4 cup and 2 tablespoons of **olive oil**, divided
• 1 slice of **bread**
• 1/2 cup of **red onions**, sliced
• 1/4 cup of **pancetta**, diced
• Salt and pepper to taste

How to Make Roasted Brussels Sprouts With Red Onions and Pancetta

1. Preheat your oven to 350°F (175°C). While it warms up, grab a large plastic zippered bag. Toss in the halved Brussels sprouts, 3 cloves of pressed garlic, and 2 tablespoons of olive oil. Give it a good shake until everything’s nicely coated.
2. Spread the Brussels sprouts out in an ovenproof dish. Pop it in the oven and roast for about 40 minutes. They should come out tender with a golden brown hue and a heavenly aroma.
3. Meanwhile, take a pan and heat up 1/4 cup of olive oil over medium heat. Once it’s warm, fry the slice of bread until it’s golden on both sides. Trust me, this will be our crispy topping magic in just a bit.
4. Set that bread aside. In the still-warm pan, add the sliced red onions. Give them a quick sauté for about 3 minutes until they slightly soften but still have a bite. You’re aiming for them to be fragrant but not mushy.
5. Toss in the diced pancetta with the onions and let them mingle for another minute. The pancetta should release its flavors but not get overly crispy.
6. When the Brussels sprouts have roasted to perfection, add them to the pan. Heat everything together for about 3 minutes, stirring gently so the flavors blend without turning into a mushy mess.
7. In a food processor, blitz the fried bread with 1-2 cloves of garlic until you have a coarse crumb. Sprinkle this over your Brussels sprouts and finish with a final drizzle of olive oil for good measure.

Cook’s Notes

Roasting Brussels sprouts is all about the timing. Make sure they’re cut evenly so they cook at the same rate. You want them tender but not mushy, with just enough caramelization to bring out their natural sweetness. This dish is fantastic fresh out of the oven, but if you have leftovers (and that’s a big if), they keep well in the fridge for about two days. Just reheat them gently so you don’t lose that delightful texture. And if you’re a planner, you can prep the Brussels sprouts and onions in advance—store them separately and combine everything just before serving for peak freshness.

Make It Your Own

• Substitute the pancetta with **crispy tofu** for a vegetarian version that’s just as satisfying.
• Swap the red onions for **shallots** if you want a milder, slightly sweeter flavor.
• Add a handful of **parmesan cheese** just before serving for a cheesy twist.
• Mix in some **dried cranberries** after roasting for a pop of sweetness that pairs wonderfully with the savory elements.
