If I were to confess some of my guilty pleasures in life, then these brussels sprouts gratin photographs would convey much of what I’m already about to say. Warm melted cheese, gooey-salty-decadent-calorie-laden cheese on top of perfectly fresh and healthy vegetables should be illegal. I think of this often when a gorgeous bowl of green veggies gaze back at me with fresh, vibrant eyes. Instead of reaching for the steamer and ideas of a raw salad, I reach for the rind of parmesan cheese, cream and block of butter.Cheesy Brussels Sprouts Gratin Recipe | Brussels Sprouts Casserole (1)

A Family Favorite Brussels Sprouts Gratin Recipe

Over 98.6572% of the time I prepare my vegetables very simply in a light saute or raw, crunchy salad. This is how I appreciate my vegetables the most and sums up the way I ate as a vegetarian for almost twenty years. But when the air begins to crisp up to cooler embrace, I sense that Fall is near. That’s when I’m guilty of killing my vegetables in a casserole pool of cheese and cream.Knowing when to stop eating is something I’m still lacking at. My mind tells me that if the food is delicious, eat another plate before it goes to waste.

A Cheesy Brussels Sprouts Treat for the Holidays

Balance is something I’ve always been thoughtful of and with all the travel we’ve been on, I realize that I’ve ignored the gym more than I should. Perhaps it’s the lack of fitness and exercise that makes eating two portions of food laden with guilt. I’m putting exercise back on my priority list before the holiday season feasting begins.Thankfully I don’t eat my vegetables like this every day, but when I do, I really appreciate every bite of dreamy, rich decadence. And then I always try to remember that there’s vegetable hidden somewhere in all this cheesy mess.

My goal for the next few months is to get back on cardio track again so that I can enjoy more of these warm, cheesy casseroles. This recipe for Brussels sprouts gratin is one of my favorite Brussels sprouts dishes for the fall because there’s comfort in every bite. Guaranteed this will be at on our Thanksgiving menu because it’s so simple, wonderful and a pleasure to eat.

FAQs

Why do you soak Brussels sprouts before cooking? ›

Not only can soaking make the centers more malleable, but the water that's absorbed into them will create a steaming action, whether you choose to roast, saute, or make your Brussels sprouts in your air fryer. The steam can help to ensure the cooking is even throughout the Brussels sprout.

Why are my brussel sprouts soggy in the oven? ›

Not using enough oil.

The other secret to ridiculously crispy Brussels sprouts is tossing them in plenty of oil. We like to use olive oil, but plain vegetable oil is great too. If the sprouts are well-coated, they'll caramelize and char instead of simply softening in the oven.

Do you need to blanch brussel sprouts before baking? ›

Like all cabbages, Brussels are unavoidably fibrous and dense. You must overcome this by either cooking them in salty water until fork tender (blanching), or by roasting at a high (over 425F) temperature for upwards of 20 minutes. To guarantee great texture, do both!

How many hours sprouts should be soaked? ›

The norm is 8-12 hours, but some soak for only 20 minutes, some occasionally soak in warm or hot water and for more or less time - Check the seed information pages for the seeds you are sprouting. Skim off any non-seeds that are floating on the water*.

How long should you soak Brussels sprouts in salt water? ›

Contributed by Whole Foods Market, Inc. To prepare, soak Brussels sprouts in a bowl of cold, salted water for 20 minutes. Preheat oven to 400°F.

What gives Brussels sprouts a better taste? ›

About 30 years ago, a Dutch scientist identified the chemicals that made brussels sprouts bitter. He selected seed varieties with lower levels of the bitter chemicals and bred new high-yielding varieties that tasted less bitter.

What do brussel sprouts do to your body? ›

Eating Brussels sprouts along with other good sources of fiber — like other vegetables, fruits, and whole grains — can help you meet your fiber needs. Brussels sprouts are high in fiber, which can promote regularity, support digestive health, and reduce the risk of heart disease and diabetes.

When not to use brussel sprouts? ›

If any of the leaves have brown spots or are yellowing, it's a sign of early spoilage. If you remove the blemished leaves and the interior looks OK, you can still use the sprout. However, if the interior leaves are also showing blemishes or yellowing, it's best to toss it (or compost it, if you can).

Why are my brussel sprouts not getting crispy in the oven? ›

Why Are My Brussel Sprouts Not Crispy? Spread them out into a single layer on a rimmed baking sheet to avoid overcrowding. If they're too close together, they'll steam instead of roast which stops the crisping process.

Why do brussel sprouts taste bad sometimes? ›

The bitter taste of Brussels sprouts comes from compounds called glucosinolates and their degradation products, he explains. These bitter tasting compounds are an important part of the plant's defence mechanism against leaf-eating enemies, such as insects, nematodes, slugs, and herbivores, like pigeons and deer.

Can you overcook Brussels sprouts? ›

For best results, cook sprouts until just tender, never mushy. Overcooking produces the offensive odor associated with Brussels sprouts. It's caused by the release of sulfur-containing compounds. Overcooking also causes them to turn a drab olive green.

Do you flip Brussels sprouts in the oven? ›

Toss until the Brussels sprouts are evenly coated, then spread them out in an even layer on the baking sheet. Sprinkle evenly with a few generous pinches of salt and pepper, to taste. Then go around and flip each of the Brussels so that they are cut-side-down.

Should you boil Brussels sprouts before baking? ›

Your first step should always be to blanch the brussels sprouts. This is basically when they get submerged in boiling water just for a few minutes, not until they're fully cooked, but just enough to take away some of the bitterness. Blanching also softens them and preserves their beautiful bright green color.

How many Brussels sprouts per person? ›

Sprouts on the stalk will stay fresher longer than sprouts that have been picked off and sold loose. Plan on about 1/2 pound (8 ounces) of raw brussels sprouts per person.

How do you get bugs out of Brussels sprouts before cooking? ›

Brussels Sprouts

Get them ready for your plate by placing the sprouts in a bowl filled with warm water and let them soak for about 10 minutes — this will flush out the dirt and any lurking pests. Give these crispy air fryer parmesan Brussels sprouts a go, once you do.

Should sprouts be soaked? ›

However, the natural agents that protect them from early germination can wreak havoc in our digestive system. Soaking and sprouting replicates germination, which activates and multiplies nutrients (particularly Vitamins A, B, and C), neutralizes enzyme inhibitors, and promotes the growth of vital digestive enzymes.

Why won't my Brussels sprouts get crispy? ›

Roast the Brussels Sprouts at high heat

If you don't hear them crisping up in the oven, add a little more oil and roast them for a few more minutes until your desire crispiness is achieved!
