Can you dehydrate Brussels sprouts whole?

You can, but it's best to halve or quarter them. Whole sprouts take longer to dry and often don’t dehydrate evenly unless sliced.

Do Brussels sprouts need blanching before dehydrating?

It’s not required, but blanching for 3–4 minutes can help preserve color, reduce bitterness, and shorten drying time.

Quick Prep Tips to Get Your Sprouts Ready for Dehydrating

Rinse the sprouts first. If you need to peel the outer layers of the sprouts, just cut off a bit of the hard-stem base to make peeling off the outer leaves a little easier.

This gives you a nice flat bottom so you can safely cut the Brussels sprouts in half, then follow the dehydrating instructions below.

Step-by-Step: How to Dehydrate Brussels Sprouts the Right Way

  1. Remove the small outer leaves and rinse if necessary under cold water. Slice them in half.
  2. Arrange on your food dehydrator trays.
  3. Turn on your food dehydrator and set the temperature between 125°F and 135°F (or per your food dehydrator's instructions).

Drying Time for Brussels Sprouts: What to Expect

  • Fully dehydrated sprouts will be wrinkly and crispy when fully dried.
  • Drying time: between 6-8 hours.

Sauté or Pan-Fry: The Tastiest Way to Use Sprouts

Brussels Sprouts frying in a pan with sweet country ham

I know many folk turn their noses up at Brussels sprouts—yes, I know they are quite a pungent, bitter vegetable, but you can make them taste a little sweeter by frying 'em up in a pan with slices of sweet country ham.

I can only imagine how good the sprouts are with the sweetness of the ham!

I have one of Gordon Ramsay's excellent cookbooks. I was learning how to cook a turkey properly one Christmas. He had a brilliant suggestion: sauté sliced Brussels sprouts in a pan along with diced bacon. Now you're speaking my language. Bacon. Bacon. Bacon!

Grow Your Own Brussels Sprouts (Here’s How!)

Brussels sprouts are a type of cabbage that is typically grown in cool climates. They are planted in the spring and harvested in the fall. Brussels sprouts grow best in well-drained soil that is rich in organic matter.

The plants should be spaced about 18 inches apart. When the Brussels sprouts are about 2 inches in diameter, they are ready to be harvested.

To harvest Brussels sprouts, cut the stalk about an inch below the sprout. Be sure to leave at least two leaves above the sprout so that it can continue to grow. Brussels sprouts can be stored in a cool, dark place for up to two months.

Cooking Brussels Sprouts: Boil, Roast, or Bacon-Wrap ’Em

Cooking Brussels sprouts is easy. Simply wash them and remove any damaged leaves. Cut the sprouts in half and cook them in boiling water for 3-5 minutes.

You can also roast Brussels sprouts in the oven. Simply toss them with olive oil and seasonings, and roast at 400°F for 20-30 minutes.

To me, they can be very strong tasting. To combat that a tad, add crumbled-up bacon to them after cooking and slicing (as mentioned in earlier).

Another way to eat yer sprouts is to wrap them in bacon a la Gordon Ramsay (mentioned earlier). Get a bacon rasher (a slice) and cut it down the middle then wrap it around the sprout and tuck in the end to keep the bacon in place. Bake as above.

What’s a “Rasher” and Why Bacon Makes Sprouts Better

If you're wondering (like I was) where the word "rasher" came from, I called on ClaudeAI to help me out. He said it derives from the Old French word "rasche" meaning "portion."

Claude added - and I really like this: A rasher is hastily cooked meat or burned meat - often cooked quickly in a pan over high heat. OK - like when we do something "rash" - in haste - it's usually done on the spur of the moment, i.e. "rashly" and often with regret!

I know I've eaten lots of bacon "rashers," Ha!

Why They’re Called Brussels Sprouts (Hint: It's Not a Typo)

As you may have guessed, Brussels Sprouts are named after the city of Brussels in Belgium. They were first cultivated there in the 13th century.

As a kid, I used to call them Brussel Sprouts without the last "s" in Brussels. It seems I never put "two and two together" back then - that they were sprouts from Brussels!

Why Do Brussels Sprouts Taste So... Bold?

Brussels sprouts have a strong, cabbage-like taste because they are in the same plant family as cabbage. They also contain a compound called glucosinolate, which gives them their characteristic flavor.

So there you have it. Get busy dehydrating these tasty treats today and enjoy them year-round. They're not just for Christmas or Thanksgiving anymore!

Brussels sprouts aren’t just for the holidays anymore — once dehydrated, they’re ready to join your pantry lineup for everyday meals. Try them in soups, pan-fried dishes, or rehydrated in a quiche or casserole.
