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 brussel sprouts before cooking? ›

The soak time tenderizes the sprouts so the middles are softer. Don't worry, they won't be soggy! I would never do that to you. If, like me, you don't mind some chew to your sprouts, you don't need to soak the Brussels sprouts prior to cooking.

Why do my brussel sprouts get mushy in the oven? ›

Moisture is the enemy of crispiness.

There's nothing wrong with soft and chewy Brussels, but if your goal is the type of crispy Brussels that they're serving at your favorite bistro you MUST thoroughly dry the surface of the sprouts before sautéing and/or roasting them. If they are wet they will steam instead of crisp.

How do you make Brussels sprouts not mushy? ›

The easiest and best way I know is to roast at high temperature. Trim the woody ends off the sprouts, and if they're large, cut in half. Toss in a bowl with salt, pepper, olive oil. Spread out on a sheet pan and put in a 500°F oven for 20 minutes, reaching in with a spoon or spatula to turn them over at least once.

Are brussel sprouts good for your gut health? ›

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.

How long should I soak brussel sprouts? ›

It won't take a lot -- just add 1 tablespoon of salt per 1 quart of water and toss in trimmed and halved Brussels sprouts. Soaking the sprouts in salt water doesn't take long --10 to 30 minutes is plenty long enough to soften up the centers.

How long should you soak brussel 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.

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

If you want your roasted Brussels sprouts to be seriously crispy, you need to crank up the heat. Roasting at a low temperature won't allow them to brown properly, so you want to get that oven nice and hot before tossing in your baking sheet. Follow this tip: Roast Brussels sprouts at a minimum of 400°F.

Why do brussel sprouts taste bad to some people? ›

"People with certain genetic variants in the TAS2R38 gene can detect bitter taste more than others and therefore may be more likely to dislike sprouts,” 23andMe senior product scientist Alisa Lehman recently told the Daily Record. "There are many factors outside genetics that play a part in the foods we like.

Should you cut brussel sprouts in half before baking? ›

To maximize the flat areas, which get the most crispy surface area, cut your Brussels sprouts in half. If your Brussels sprouts are very small, you can leave them whole (and if they are very large, quarter them).

Why aren't brussel sprouts bitter anymore? ›

Over the last twenty years, farmers have mellowed the "unpleasant" flavor of brussels sprouts by breeding a vegetable that contains fewer bitter compounds or glucosinolates. So, brussels sprouts just taste better than they used to when we were kids. The rub is that glucosinolates help protect sprouts against pests.

When should you not eat brussel sprouts? ›

Throw out fresh brussel sprouts that have a foul odor, yellow or wilted leaves, a mushy or slimy texture, or dark spots. Use fresh brussel sprouts within 1–2 weeks of getting them. Store the brussel sprouts in a plastic bag inside your fridge, and wash them before cooking them.

Why does my stomach hurt so bad after eating brussel sprouts? ›

Do brussel sprouts clean your colon? ›

Along with spinach & kale being optimal choices, green olives, asparagus, Brussels sprouts, cabbage, celery, collard greens, sea vegetables like seaweed, leeks, peas, and Swiss chard are all high in chlorophyll, which means they can help cleanse your digestive tract and detoxify your liver.

Do sprouts need to be soaked? ›

Soaking: Think of soaking as the initial step before actually sprouting a legume, grain, nut or seed. Many people soak beans before cooking to cut down on cooking time and reduce compounds that may cause gasiness in our digestive systems (although it's not completely necessary, it's definitely recommended).

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.

How do you get the bitterness out of brussel sprouts? ›

A splash of lemon juice, or even apple cider vinegar, works wonders on bitter sprouts. Another key ingredient is fat, which helps Brussels sprouts to crisp up.
