Crispy Kale, Brussels Sprouts, and Potato Hash Recipe (2)

Why It Works

  • Par boiling the potatoes before frying them ensures creamy interiors.
  • Kale and Brussels sprouts add nutty notes as they crisp in the pan.
  • The combination of onions and hot sauce lend sweet and spicy notes.

There are only a few things in life that can't be made at least a bit better by topping them with a soft cooked egg. Off the top of my head I can only think of three: great novels (traditional paper or electronic), hair cuts, and ice cream sundaes. That's about it.

Things that are definitely in the better-with-an-egg camp: Steak. Pasta. Hash.

It's the latter we care about today. I'm a hash fiend, hard core. It's what I make when all I have is a few odds and ends in the fridge and a couple of eggs. Cut some vegetables up just right, cook them until browned and crisp, crack an egg on top and cook it until just set, and you've got a meal that's easy enough to make for breakfast but satisfying enough for a light dinner.

This version starts out as a traditional potato hash. The secret to super crisp potatoes that are golden on the exterior and creamy in the middle is to par-cook them in water to tenderize and add moisture to gelatinize their starches before frying them in a skillet to crisp up their exterior.

A few minutes before the potatoes are done crisping, I add handfuls of shredded brussels sprouts and kale, along with some sliced onions. It looks like a lot of stuff going into a moderately small pan, but those greens will very quickly wilt and cook down, shedding their moisture and crisping as they do, turning their green flavor into something rich, sweet, and nutty.

If all goes well, and there's no reason to think that it shouldn't, your kale and sprouts should finish cooking down just as your potatoes achieve maximum crispness and your onions start to take on hints of sweetness to balance out the heat and tang of the hot sauce you stir in at the very end.

For the eggs, you can poach them using our foolproof method if you'd like, but it's much easier just to break them directly into wells you form in the hash and finish them off in the oven with just a drizzle of olive oil.

This hash smells so good coming out of the oven that my wife literally clapped her hands when I brought it to the dinner table. That's a pretty good return for about a half hour's worth of work, and an admittedly strange thing for her to do.

The jury is still out on whether she's better with or without a soft cooked egg on top, but I'll make sure to figure it out one night while she's asleep and report back. For science.

Cook35 mins

Total35 mins

Serves2 servings

Ingredients

  • 3/4 pound Yukon Gold potatoes, cut into 3/4-inch chunks

  • Kosher salt and freshly ground black pepper

  • 3 tablespoons vegetable or canola oil, divided

  • 12 medium Brussels sprouts, finely sliced (about 1 1/2 cups)

  • 2 cupschopped, tightly packed kale leaves (about 1/2 bunch)

  • 1 small onion, finely sliced

  • 1 teaspoon hot sauce, such as Frank's Red Hot

  • 2 tablespoonsminced fresh parsley leaves, divided

  • 1 tablespoon extra-virgin olive oil

  • 2 eggs

Directions

  1. Adjust oven rack to middle position and preheat oven to 450°F. In a medium saucepan, cover potatoes with cold salted water and bring to a boil over high heat. Reduce to a simmer and cook until barely tender, about 5 minutes after coming to a boil. Drain potatoes in a colander and let drain for 2 minutes.

  2. While potatoes drain, heat 2 tablespoons vegetable or canola oil in a medium non-stick or cast iron skillet over high heat until shimmering. Add potatoes, season with salt and pepper and cook, stirring and tossing occasionally, until well-browned on most sides, about 5 minutes. Add remaining vegetable or canola oil, brussels sprouts, and kale leaves and cook, folding occasionally, until kale and sprouts are starting to wilt, about 2 minutes. Add onions and continue to cook, stirring and folding occasionally, until all vegetables are softened and starting to crisp, about 8 minutes. Stir in hot sauce and half of parsley, season to taste with salt and pepper, and remove from heat.

  3. Make two wells in the vegetables and drizzle each with a few drops of olive oil. Add 1 egg to each. Sprinkle with salt and pepper and drizzle with remaining olive oil. Transfer to oven and cook until eggs are barely set, about 4 minutes. Sprinkle with remaining parsley and serve immediately.

FAQs

Why won't my brussel sprouts get crispy? ›

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 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.

How do you crisp soggy brussel sprouts? ›

It's as simple as spreading the leftover Brussels sprouts in a single layer on a baking sheet (use two to avoid overcrowding if there's a lot) and heating them in a 350°F for 10 to 12 minutes. When the sprouts come out of the oven they'll be hot and crispy all over.

What is a cross between Brussels sprouts and kale? ›

Kalettes (formerly known as Flower Sprouts, Petit Posy, Brukale, or Brusselkale) are a hybrid plant brand name for kale sprouts. Bred using traditional breeding techniques, they are a cross between kale and Brussels sprouts. The plant is touted as being a highly nutritious vegetable that may be eaten as raw or cooked.

Do you need to blanch brussel sprouts before frying? ›

Parboiling Brussels sprouts before frying is a good technique to ensure they cook evenly and become tender on the inside while allowing for a crispy exterior when fried. However, it's not always necessary but we think it works here to create a soft middle and crisp exterior in the pan.

Why are my brussel sprouts still hard after cooking? ›

Without oil, Brussels don't brown and soften—they dehydrate. Its also possible that they simply need more time in the oven. Cooking times vary depending on their size. A cooked Brussels sprout should be pierced easily with the tip of a sharp knife.

Should you cut brussel sprouts in half before cooking? ›

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).

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.

How long should I soak my 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.

Should I boil my brussel sprouts before frying? ›

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 do you crisp up already cooked brussel sprouts? ›

Leftover Brussels sprouts can be warmed up in the microwave, but if you want there to be some crispness to the caramelized edges, you can warm them in a skillet on the stove. Alternatively, you can spread the leftovers in a single layer on a sheet pan and warm in a 350°F oven until warmed through.

Do you cook brussel sprouts face up or down? ›

Roast 'em! Our two rules: place and space! Place them cut side down to create that slightly crunchy exterior and soft interior. Space them out evenly so they don't steam–a crowded sheet pan party is not where your brussels want to be.

Which is healthier broccoli or brussel sprouts? ›

While broccoli may have a higher count of calories, fat, and carbs, it is richer in calcium, iron, and pantothenic acid (a B vitamin that does wonders for healthy hair), and has a bit more potassium. Brussels sprouts, on the other hand, are lower in sodium.

Why do you put a cross in the bottom of brussel sprouts? ›

Some people swear by cutting a cross in the bottom of each sprout, which they believe allows them to cook all through – but it's not necessary, and you'll save time if you don't.

Why are brussel sprouts only eaten at Christmas? ›

Sprouts were still much of a novelty well into the 19th century. However, their appearance in late autumn made them an ideal fresh vegetable for the table just as the idea of having a large feast to celebrate Christmas Day was taking root in Victorian sensibilities. They were a match made in heaven, at least for some.

Why are my brussel sprouts not forming tight heads? ›

The usual cause is poor soil, lack of growth and especially the use of non-hybrid cultivars. Only hybrid cultivars can be relied on to produce firm sprouts. Excessive nitrogen fertiliser is not implicated in loose sprout formation.

Why are my roasted brussel sprouts soft? ›

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.

Why are my sprouts soggy? ›

Watering just right is key to preventing mushy Brussels Sprouts leaves. It's like a dance with nature—know the steps. Water thoroughly until it drains from the bottom, then let it be. Overwatering is a no-go; it's the fast track to Soggyville.

What's wrong with my brussel sprouts? ›

Alternaria is a common disease that causes spots on leaves. Black rot causes yellow triangles on the edge of leaves. Clubroot attacks the roots of brussel sprouts, causing roots to be swollen and plants to be stunted.
