The bacon starts to sizzle before the Brussels sprouts ever hit the pan, and that rendered fat is what gives this side its savory start. I used to toss everything together at once, but the sprouts were ready before the bacon got crisp. For these crispy bacon Brussels sprouts, cooking the bacon first gives each part the time it needs.

After the bacon comes out, I leave a tablespoon of drippings on the baking sheet and use it to roast the sprouts cut-side down. That flat surface gets direct contact with the hot pan, so it browns while the centers turn tender. The olive oil helps coat the sprouts, and a little salt and pepper keep the flavors clear.

The bacon goes back in for the last few minutes, just long enough to warm through without giving up all its crunch. You get bronzed edges, soft centers, and little crisp bites of bacon tucked between the leaves.

Why the Cut Side Needs the Pan, Not the Air

Brussels sprouts have plenty of folded leaves, but the broad cut face is where you can get an even, deeply browned surface. Setting that side against the baking sheet gives it steady contact with the heat. If the rounded side faces down instead, the sprouts can still cook through, but you miss the flat, caramelized patch that makes each half taste roasty rather than simply steamed.

That direct contact also explains why it helps to dry the sprouts after washing them. Water sitting on the cut surface has to evaporate before browning can begin, and a wet surface tends to soften before it colors. Pat them dry, then arrange them cut-side down in a single layer so the hot pan can do its work. The goal isn’t to char every leaf; look for browned faces and tender centers, with some outer leaves turning darker at the edges.

The bacon and sprouts cook in stages for a reason, too. Bacon needs an initial stretch in the oven to render its fat and become crisp. The sprouts then roast in the drippings, and the cooked bacon returns near the end, so it warms without spending the whole roast softening beside the vegetables.

What Bacon Drippings, Olive Oil, and Fresh Sprouts Each Bring

• Brussels sprouts — Choose firm sprouts with compact leaves and no soft, yellowing spots. Fresh sprouts are the right choice for this roast because they can brown on the cut face while their centers turn tender; frozen sprouts release more moisture as they thaw and won’t give the same browned texture. Trim the ends and halve each sprout evenly so the pieces roast at a similar pace.
• Bacon — Bacon brings both the crisp pieces and the rendered fat that seasons the pan. A familiar grocery-store bacon works well; the important part is cutting it into the specified pieces so it cooks evenly. If it hasn’t rendered much fat by the time it turns crisp, don’t add extra bacon fat or oil to the pan—the olive oil already coats the sprouts.
• Olive oil — The oil helps the seasoning cling and coats any cut surfaces that don’t pick up drippings. A standard olive oil is fine here; there’s no need to use a specialty bottle for roasting. Toss the sprouts thoroughly in the bowl before arranging them, rather than pouring oil directly onto the baking sheet.
• Kosher salt and black pepper — These season the sprouts without hiding the bacon’s savory flavor. The bacon contributes salt as it cooks, so keep the measured salt as written rather than salting the finished pan again before tasting.

The Two Oven Stages That Keep the Bacon Crisp and the Sprouts Brown

Render the bacon before the vegetables go on

Heat the oven to 425°F and spread the bacon pieces on a rimmed baking sheet. Bake them for 12–15 minutes, until the pieces are crisp and the fat has rendered. Move the bacon to a paper towel-lined plate, then leave one tablespoon of drippings on the pan. If the pieces are still bendy rather than crisp, give them the time they need within that range before transferring them.

Coat the sprouts without soaking them

In a large bowl, toss the trimmed, halved Brussels sprouts with the olive oil, kosher salt, and black pepper. They should look lightly coated, not slick with oil. Spread them on the baking sheet with the cut sides against the pan. If the bowl has a puddle of oil at the bottom, toss once more so it doesn’t all land beneath a few sprouts.

Roast until browned and tender

Roast the sprouts for 20–25 minutes, watching for browned cut faces and centers that yield when pierced. The exact point within that range depends on the size of the halves and your oven, so use the color and tenderness together rather than relying on the clock alone. If they look pale, give them more time in the oven; taking them out while they’re still firm leaves the centers undercooked.

Return the bacon for the final minutes

Add the cooked bacon to the baking sheet for the final 5 minutes of roasting. That short finish warms the bacon and lets its flavor mingle with the sprouts without leaving it in the oven for the full vegetable roast. The pan is ready when the sprouts are tender and browned and the bacon is hot.

The Brussels Sprouts Questions That Come Up at the Oven

Crispy Bacon Brussels Sprouts

Crispy bacon Brussels sprouts are roasted at 425°F until the cut sides are browned and tender. Bacon drippings add savory flavor, while crisp bacon goes back on the pan for the final 5 minutes.

• 0.25 tsp kosher salt
• 0.25 tsp black pepper

Equipment

• 1 rimmed baking sheet

Method

 

1. Preheat the oven to 425°F.
2. Spread the bacon on a rimmed baking sheet and bake for 12–15 minutes, until crisp and the fat has rendered.
3. Transfer the bacon to a paper towel-lined plate and leave 1 tablespoon of drippings on the pan.
4. In a large bowl, toss the Brussels sprouts with the olive oil, salt, and pepper.
5. Arrange the Brussels sprouts cut-side down on the baking sheet.
6. Roast for 20–25 minutes, until the sprouts are browned and tender.
7. During the final 5 minutes of roasting, add the bacon to the baking sheet.

Notes

For the best browning, arrange the sprouts cut-side down with space between them. Refrigerate leftovers for up to 4 days; freezing is not recommended because the sprouts can soften. For a vegetarian variation, use plant-based bacon.
