Keto Cabbage Hash Brown Casserole (You’ll Want Seconds)

If you’ve ever tried peeling cabbage with half a brain full of dinner ideas and zero motivation, you already know how underrated simple cabbage recipes really are. Now, throw in hash browns, Irish-style comfort food, and that low-carb itch you’re trying to scratch—this Keto Cabbage Hash Brown Casserole might just fix all of that in one go.

It’s the kind of dish that makes you pause after the first bite, give a slow nod, and think: “Yup. This is staying in the rotation.”

So grab a cast iron or whatever oven-safe thing isn’t in the dishwasher, and let’s get into it.

What You’ll Need (Nothing Fancy)

• 1 small green cabbage, shredded thin (about 6 cups)
• 3 large eggs
• 1 onion (yellow or red—no one’s judging), sliced
• 1 teaspoon garlic powder
• 1/2 teaspoon black pepper
• 1/2 teaspoon sea salt
• 1/2 teaspoon smoked paprika
• 2 tablespoons olive oil
• 1/4 cup almond flour (optional, helps hold shape)
• 1/2 cup shredded cheddar (sharp Irish cheddar hits hard here)
• 1 tablespoon butter (for greasing)

No potatoes, no carrots, no turnips. But if you’re looking for those versions—hang tight, I’ll get to some swaps later using ideas from classic Cabbage Potato Carrot Recipe or Red Turnip Recipes that work with this base.

How to Make this Cabbage Hash Brown Casserole

Step 1: Cook the Cabbage & Onion

Heat olive oil in a big ol’ pan on medium heat. Toss in your sliced onion and shredded cabbage. Stir every couple of minutes. Don’t rush it. The cabbage softens and starts getting those slightly crispy brown bits around the edges after 10–12 minutes.

Add garlic powder, paprika, salt, and pepper. Stir again.

This part smells like a cross between Irish grandma’s kitchen and a campsite breakfast.

Step 2: Build the Casserole Mix

Crack your eggs into a large bowl and beat them like you’re mad. Add the cooked cabbage and onion mix. Sprinkle in almond flour if using. Mix it all up so everything’s coated. It’ll look sloppy—that’s perfect.

Step 3: Oven Time

Grease your baking dish with butter. Pour the cabbage mixture in. Spread it flat. Top with shredded cheddar. Bake at 375°F (190°C) for 30 minutes or until the top is golden and crisp on the edges.

Let it cool for five. Then cut, serve, eat.

Why This Works

You get all the crispy, cheesy, cozy comfort of hash brown potatoes recipes—without the starchy crash. This keto-friendly version still gives you those hash brown vibes. That crispy edge, that savory center. It’s like a mash-up between cabbage hash browns and your aunt’s best hashbrown recipes from back in the day.

No regrets. No carb coma.

How I Eat This (Trust Me, I Tried ‘Em All)

• Irish Casserole Recipes Night: We did a St. Patrick’s Day “green dinner” lineup, and this was the only dish everyone went back for. Kids, teens, meat-lovers, keto folks. Didn’t matter.
• Next-Day Brunch: Slice leftovers into squares, fry ‘em like hash browns in butter. Throw a fried egg on top. Boom—better than most Irish food recipes I’ve tried on a plate before noon.
• Tailgates and Potlucks: Bring this. It travels well. Doesn’t need to be piping hot to still hit.
• Side with Beanee Weenee Recipe: Weird combo? Maybe. But baked beans and cabbage casserole is secretly a win.

Want to Add Potatoes or Carrots?

I get it. You’re maybe keto-ish, not keto-fanatic. Or maybe you’re just looking for cabbage potato carrot recipe ideas that lean cozy.

Here’s what to do:

• Grate 1 small potato and 1 carrot. Mix it in raw with the cabbage before baking. This still works. It adds natural sweetness and that good potato starch bite. Your grandma would probably call it rustic. Your keto app won’t love it—but hey, not everything has to be low-carb every time.

Red Turnip or Not?

Let’s talk swaps.

Some folks out there swear by red turnip recipes as a way to sneak in that root-veg earthiness without loading up on carbs.

So yeah—grate one peeled red turnip. Sauté with the cabbage. You’ll get more depth, a bit of bite, and it plays nice with the Irish cheddar on top. Bonus: it turns everything slightly pinkish. In a good way.

Meal Ideas to Go With this Keto Cabbage Hash Brown Casserole

This casserole can carry a meal, but it also tags along nicely with:

• Irish cabbage recipes like boiled cabbage with bacon
• Corned beef (duh)
• Fried eggs
• Sausages
• Stew-style Irish side dishes
• Sautéed kale or spinach if you’re riding the green dinner ideas wave

And if you’ve ever made a beanee weenee recipe from a can and felt like it needed backup—this casserole is that backup. It makes that meal feel less like a cry-for-help dinner and more like a plan.

Make It More Irish (The Authentic Kind)

This recipe leans heavy on flavor, but if you want to lean into Irish recipes authentic dinner style, here’s how to spin it:

• Use Kerrygold butter. The real stuff.
• Sub Irish rashers (like thick bacon) for a savory top layer.
• Add a touch of ground mustard seed or a splash of malt vinegar for that pub kick.

Suddenly, your Irish casserole recipes board on Pinterest just got better. Homemade, real, and still sticks to the ribs.

No Cheese? No Problem.

Skip the cheddar and sprinkle chopped parsley or green onion after baking. Keep it dairy-free. Still tasty. And still a solid option if you’re trying to fit more Irish vegetable recipes into your life.

Storage and Reheating

Fridge life? 4 days easy. Reheat in oven at 350°F till warm, or pan-fry slices in butter if you like that extra crisp. Microwave? Meh. It’ll work. But it won’t do it justice.

Conclusion

This isn’t fancy food. This isn’t a recipe built to show off. It’s built to feed you, keep it simple, and still feel like home.

Whether you’re mixing up your list of cabbage recipes, trying to copy your Nan’s old cabbage Irish recipes, or just need a new idea for recipes with hash brown potatoes that doesn’t come out of a box, this one’s a keeper.

People will ask for the recipe. And you’ll forget where you saved it. But now, it’s here.

If someone tells you cabbage is boring, send them this. If they don’t change their mind, they’re probably the kind of person who peels hard-boiled eggs under hot water and complains about everything.

You’re not that person.

Now go make this casserole.
