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.

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? ›

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.

Why do you soak brussel 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.

What should not be planted with brussel sprouts? ›

Tomatoes and other nightshades, like eggplants, need a lot of nutrients to grow. Brussels sprouts are also heavy feeders, so two should not be planted next to each other as they will compete for the same nutrients.

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.

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.

Should I boil my brussel sprouts before roasting? ›

Unlike other vegetables, Brussels sprouts can be parboiled (even a day ahead) to reduce the roasting time without hurting their texture. That means the sprouts can be popped in the oven while the meat is resting before carving. Of course, if the main course is grilled or pan-cooked, the oven will be free for roasting.

Who should not eat brussel sprouts? ›

Although a healthy vegetable, consuming too many Brussels sprouts can be unsuitable for people on anticoagulants since it contains vitamin K, which results in blood clotting. Another issue with consuming Brussels sprouts excessively is that it can lead to gas and bloating.

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.

What is a good companion for brussel sprouts? ›

Onions and Garlic:

These pungent alliums are great companions for Brussels sprouts. Garlic and onions have strong scents are effective in deterring common pests like aphids and some beetles. Plus, they occupy a different space in the garden bed, ensuring efficient use of space.

Do you roast brussel sprouts cut side 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.

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.

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 Brussel Sprouts always soggy? ›

They are one of my favorite veggies in the whole wide world! When overcooked, Brussels sprouts turn mushy and release excess sulphur (the thing that makes cabbage and Brussels sprouts smell like cabbage and Brussels sprouts)—not good eats.

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.
