The bacon starts to sizzle before the Brussels sprouts even hit the pan, and that first batch taught me not to rush it. If the pieces come out before they’re crisp, they soften once they meet the hot sprouts. Letting the bacon brown in the skillet first gives this side its salty crunch, while the oven takes care of the deep color on the vegetables.
For these Crispy Bacon Brussels Sprouts, the cut sides need direct contact with the baking sheet. I toss the sprouts with olive oil, salt, and pepper, then set them cut side down in one layer. That simple arrangement lets the flat faces brown instead of trapping steam between crowded pieces. Quartering the larger sprouts helps them cook at the same pace as the smaller halves, so the finished pan has tender centers, browned edges, and crisp bacon in every serving.
Kitchen Note
The bacon should look crisp before it leaves the skillet, not just cooked through. It won’t get crunchier once it’s mixed with the sprouts, so give it the full 8–10 minutes over medium heat and let excess grease drain on paper towels.
Save these Crispy Bacon Brussels Sprouts for a side with deeply browned cut sides and crisp, savory bacon in every bite.
Cut-Side-Down Is What Gives These Sprouts Their Brown Crust
Brussels sprouts can turn soft and pale when their cut surfaces sit above the pan or when the pieces are packed together. Set each piece flat-side down and leave a little breathing room around it. The flat face stays in contact with the hot metal long enough to develop a browned crust, while the rounded side roasts through.
The large rimmed baking sheet matters here because two pounds of sprouts need room to spread out. A crowded layer holds onto moisture, and moisture works against browning. If you can’t fit the pieces in a single layer, use a second rimmed sheet rather than piling them up. The cut faces don’t all need to look identical; what you’re after is a deep golden-brown surface and a tender center. That contrast is what makes a simple roasted sprout taste complete alongside the salty bacon.
Why Thick-Cut Bacon and Fresh Sprouts Matter Here
- Thick-cut bacon — The larger pieces hold their shape as they crisp, so they stay distinct when tossed with the vegetables. A standard grocery-store brand works; look for thick-cut slices and cut them into even pieces so they cook at a similar rate.
- Brussels sprouts — Choose firm sprouts with compact leaves and trim away the dry stem ends. Smaller sprouts can stay halved, while larger ones need quartering to roast through alongside them. Fresh sprouts give the most dependable browned exterior; frozen ones release extra moisture as they roast.
- Olive oil — It coats the sprouts so the salt and pepper cling and the cut surfaces roast evenly. A regular everyday olive oil is a good fit; there’s no need to use a prized finishing oil for high-heat roasting. Avocado oil works as a neutral substitute in the same quantity, though it won’t bring the mild olive flavor.
How to Get Crisp Bacon and Deeply Browned Sprouts in One Pan
Heat the oven before prepping the tray
Set the oven to 425°F and put a rack in the center before you start roasting. A fully heated oven helps the sprouts brown instead of slowly softening in rising heat. Use a rimmed 18×13-inch baking sheet so the sprouts can sit in a single layer. The rim also keeps any loose leaves from sliding off while you move the pan.
Render the bacon until crisp
Cook the cut bacon in a 12-inch skillet over medium heat, stirring occasionally. It should take 8–10 minutes, and the pieces should look browned and crisp rather than merely pale and cooked. Transfer them to a paper towel-lined plate when they reach that texture. Don’t leave the bacon sitting in the skillet while you work on the sprouts, or it will keep cooking in the hot pan.
Coat the sprouts and arrange their flat sides
Put the trimmed, halved sprouts in a large bowl and toss them with the olive oil, kosher salt, and black pepper. Quarter the larger ones so their size is closer to the smaller halves. Spread them over the baking sheet in one layer, setting the cut side of each piece against the pan. If the pieces overlap, rearrange them before roasting; stacked sprouts won’t brown as evenly.
Roast until tender, then toss with bacon
Roast for 25–30 minutes, until the sprouts are tender and their cut sides are deeply browned. Check the thicker pieces with a fork; they should give without feeling firm in the middle. The exact shade varies with the size of the sprouts, so use the browned cut faces and tenderness as your cues. Toss the crisp bacon with the hot sprouts and serve right away.
Two Practical Ways to Adapt the Pan
Make a vegetarian version without bacon
Leave out the bacon and roast the sprouts with the olive oil, salt, and pepper. The vegetable preparation and oven method stay the same, but you’ll lose the smoky, salty contrast and crisp bites of bacon. It makes a straightforward roasted Brussels sprouts side for a vegetarian meal.
Scale it down for a smaller table
Halve each ingredient for a smaller batch and keep the sprouts spread out on the rimmed sheet rather than gathered in a small pile. Preserve the cut-side-down arrangement and begin checking near the start of the usual roasting window; color and tenderness matter more than filling the pan. Cook the bacon in a skillet sized to hold it in an even layer.
Storage and Reheating
- Refrigerator: Store leftovers in a covered container for up to 4 days. The sprouts soften, and the bacon loses some of its crunch.
- Freezer: Freezing isn’t recommended. Thawed sprouts turn softer, and the crisp browned surfaces won’t return well.
- Reheating: Spread leftovers on a baking sheet and warm them in a 425°F oven until hot, which helps the edges regain some crispness. Avoid reheating in a covered container, which traps steam and softens the sprouts further.
