Brussels Sprout Pizza With Bacon and Mustard Cream

Brussels sprouts have the worst reputation of any vegetable in America, and most of it was earned by a pot of boiling water in somebody’s childhood kitchen. Put them on a pizza, though, and something weird happens. People who swear they hate sprouts go back for a third slice.

The trick is how you cut them. Almost every Brussels sprout pizza recipe on the first page of Google halves or quarters the sprouts and roasts them first. That works, but it adds up to 35 minutes and a second sheet pan. Shaving them thin and putting them on raw gets you crispy, charred, nutty edges in the same 10 minutes the crust needs.

So I went through the ranking recipes, the extension-service guidance and a bit of brassica chemistry, and built the version I think works best in a home oven: shaved sprouts, crisp bacon, Gruyere and a reduced mustard cream instead of tomato sauce.

Why Brussels Sprouts Work on Pizza

A pizza oven is basically a roasting machine, and roasting is the one thing Brussels sprouts are great at. The Harvard T.H. Chan School of Public Health’s science-of-flavor writeup on cruciferous vegetables describes carefully oven-roasted sprouts as having a nutty, almost popcorn-like sweetness. That comes from Maillard browning, which kicks in once the surface gets past about 300°F.

Your oven at 500°F clears that bar easily. A boiled sprout never gets near it because water tops out at 212°F. That is the whole difference between the sprouts you hated as a kid and the ones on this pizza.

Sprouts also bring less water than you might think. USDA FoodData Central lists raw Brussels sprouts at 86 grams of water per 100 grams (FDC ID 170383). That is plenty, but spread thin across a pie, most of it steams off during the bake instead of pooling. If you’ve fought soggy topping problems with mushrooms or fresh tomatoes, sprouts are far more forgiving.

They also fill a seasonal gap. Most of the loaded veggie pizza ideas people reach for are summer produce. Brussels sprouts peak exactly when tomatoes are done for the year.

Shaved vs Halved: What the Ranking Recipes Do

Before writing this, I read through five Brussels sprout pizza recipes ranking on page one of a US Google search. The split was clear. Three roast the sprouts first (halved or quartered), and two put them on raw, cut thin.

Here’s why the roast-first crowd roasts first. Extension services describe a ready-to-pick sprout as about 1 to 1½ inches across, hard and compact, per the University of Maryland Extension. Harvard’s roasting guide gives halved sprouts of that size 18 to 25 minutes at 400°F. A pizza bake is half that, so raw halves come out crunchy in the middle.

Put raw halved sprouts on a pizza and you get little green marbles that roll off the slice like they’re trying to escape. Shaving solves that by making every piece thin enough to cook through in the time the crust takes. Thin shreds also have far more edge, and edges are where the char lives.

To be fair to halved sprouts, they give you bigger, meatier bites and you can roast them a day ahead. If that’s your style, follow the method on roasting vegetables for pizza, then scatter them on and bake as normal. I just think shaved is the better pizza.

How to Keep the Sprouts From Tasting Bitter

That sharp, sulfur edge comes from glucosinolates, the sulfur-containing compounds Harvard’s writeup credits for the sprout’s strong aroma and bitterness. An intact sprout barely smells of anything. Cutting, cooking or chewing breaks the cells and releases an enzyme, myrosinase, that turns those compounds into the pungent stuff.

So yes, shaving releases more of it than halving. In my read, the high-heat bake is what balances it out, because browning adds sweetness and roasty notes on top. A few more things help:

Buy good sprouts

The UMD Extension calls Brussels sprouts a fall crop and recommends harvesting after frosty weather for the best flavor. Plants that mature in hot, dry conditions can turn bitter. Translation: fall and early winter sprouts taste better than the ones you find in July.

Pick firm, bright green sprouts with tight heads. The North Dakota State University Extension fact sheet says 1 to 2 inches across, and suggests stripping off any wilted outer leaves.

Use them fresh

UMD notes sprouts keep 3 to 5 weeks in cold storage, but recommends no more than a day or two in the fridge for best flavor. NDSU says up to two weeks, with the best taste and texture in the first week. Store them unwashed and untrimmed in a breathable bag in the crisper.

Don’t overcook them

NDSU’s advice is to cook sprouts only until fork-tender to avoid bitterness. Shaved sprouts on a 500°F pizza get exactly that: done in minutes, charred at the tips, never stewed. IMO this is the strongest argument for the shaved method.

Pair them with fat, salt and acid

NDSU also points out that sprouts pair well with garlic, rich cheeses and acidic dressings. Bacon brings fat and salt, Gruyere brings richness, and the mustard and a squeeze of lemon at the end bring the acid. Every part of this pizza has a job.

The Mustard Cream Base

Tomato sauce fights Brussels sprouts. It’s acidic and wet in a way that crowds out the nutty flavor you just worked to get. A creamy base fits better, which is why the Ooni recipe uses creme fraiche and others go with blue cheese dressing. If you want a broader menu of options, here are more alternatives to tomato sauce.

My pick is heavy cream reduced with Dijon and whole-grain mustard. Use heavy cream specifically, not half-and-half. Under the federal standard in 21 CFR 131.150, heavy cream must contain at least 36 percent milkfat. That fat is what lets it simmer down into a spreadable sauce rather than turning thin and watery on the dough.

The mustard isn’t just flavor, either. Mustard seed contains a gum-like mucilage, and a 2015 study in Food Hydrocolloids found yellow mustard mucilage was a remarkably strong emulsifier: a 1 percent solution matched the surface activity of a 15 percent gum arabic solution, and its emulsions held their droplet size after 20 minutes at 194°F. That was a lab test, not a pizza, so I treat it as a plausible reason mustard cream sauces hold together well, not proof.

Reduce the cream by about a third, until it coats a spoon. Then spread it thin. Like any classic white pizza sauce, too much will bubble over the rim and puddle on your stone.

That last tip matters more than it sounds. If you’ve never done it, here’s how to shred your own mozzarella without wrecking your knuckles. For more on what gets a head start and what goes on raw, see which toppings need a head start.
