Why You’ll Love This Corned Beef And Cabbage Casserole
What I love most (besides how ridiculously easy it is to make) is how the rice soaks up all that cheesy goodness while the cabbage keeps just enough crunch. Leftovers? Even better the next day when the flavors have really gotten to know each other. Whether you’re feeding a crowd or just craving something hearty, this casserole never disappoints.
Listen, I know you’re going to adore this casserole as much as I do – and here’s why:
- Creamy dreamy goodness: That Swiss cheese sauce coats every bite in rich, velvety comfort. It’s like a warm hug for your taste buds!
- Hearty enough for hungry crowds: Packed with protein from the corned beef and fiber from the cabbage and rice, this dish actually satisfies.
- Easier than boiling a pot of water: Seriously, if you can chop and stir, you can make this. The oven does most of the work.
- Tastes even better tomorrow: The flavors meld beautifully overnight – if there are any leftovers, that is!
Trust me, this is the kind of recipe you’ll find yourself making year-round, not just on St. Patrick’s Day.
Ingredients for Corned Beef And Cabbage Casserole
Okay, let’s gather our cast of characters – these simple ingredients come together to create something magical. I’ll walk you through each one because, trust me, the details matter here!
- 2 cups cooked brown rice – Day-old rice works best here since it’s slightly drier and won’t make the casserole mushy
- 2 cups cooked corned beef, chopped – I like mine in hearty chunks, about ½-inch pieces
- 2½ cups chopped cabbage – Chop it roughly like you would for coleslaw (but no need to be perfect!)
- 3 tablespoons butter – Real butter only, please! It makes all the difference in the sauce
- ¼ cup chopped shallots – These add such lovely mild onion flavor
- 2 cloves garlic, minced – Fresh is best – I press mine right into the pan
- 3 tablespoons flour – All-purpose works perfectly for our roux
- 2½ cups milk – Whole milk makes the creamiest sauce, but 2% works in a pinch
- 2 cups shredded Swiss cheese, divided – Shred it yourself for best melting – I use about 1½ cups in the sauce and ½ cup for topping
- 1 teaspoon ground mustard – This little secret weapon makes the cheese flavor pop
- 1 teaspoon salt – Start with this and adjust to taste
- ½ teaspoon pepper – Freshly cracked if you’ve got it
- ½ cup sour cream – Adds wonderful tang and richness

A quick tip before we start cooking – measure everything out first (mise en place, as the fancy chefs say). This recipe moves quickly once the sauce starts, and you’ll thank yourself for being prepared!
How to Make Corned Beef And Cabbage Casserole
Alright, let’s get cooking! This casserole comes together in three simple parts – the base, the sauce, and the baking. Don’t let the steps fool you – it’s easier than it sounds, and I’ll walk you through each part with all my little tricks.
Preparing the Casserole Base
First things first – grab your biggest mixing bowl (I use my trusty 4-quart one) and toss in the rice, chopped cabbage, and corned beef. Here’s my secret – pat that cabbage dry with paper towels first! Wet cabbage makes for a soggy casserole, and nobody wants that. Mix everything until it looks evenly distributed – you should see little flecks of pink corned beef peeking through the rice and cabbage.
Making the Cheese Sauce
Now for the magic part – the sauce! Melt your butter in a medium saucepan over medium heat. When it’s just starting to bubble, toss in the shallots and garlic. Oh, that smell! Sauté until they’re soft and fragrant, about 4-5 minutes. Sprinkle in the flour and whisk like crazy for 1 minute – this cooks out that raw flour taste.
Here comes the fun part – slowly drizzle in the milk while whisking constantly. Keep whisking as the sauce thickens to the consistency of heavy cream. Reduce heat to low and stir in 1½ cups of Swiss cheese, the mustard, salt, and pepper. Once the cheese melts, take it off the heat and fold in the sour cream. Taste it – isn’t that incredible?
Baking the Casserole
Pour that glorious cheese sauce over your cabbage mixture and stir gently to coat everything evenly. Transfer to your greased 9×13 baking dish and sprinkle with the remaining cheese. Cover tightly with foil (shiny side down!) and bake at 350°F for 25 minutes. Then, remove the foil and bake another 5-10 minutes until the top gets those beautiful golden spots.
Let it rest for 5 minutes before serving – I know it’s hard to wait, but this helps the sauce set up perfectly. Dig in and enjoy the cheesy, comforting goodness!

Tips for the Best Corned Beef And Cabbage Casserole
After making this casserole more times than I can count (and eating even more of it!), I’ve picked up some foolproof tricks to guarantee perfection every time:
- Dry that cabbage! After chopping, spread it on paper towels and pat gently – excess moisture is the enemy of crispy-tender cabbage.
- Cheese swaps? Gruyère melts beautifully like Swiss, while sharp cheddar gives a bolder flavor. Just avoid pre-shredded – those anti-caking agents prevent smooth melting.
- Watch the clock – overcooking makes rice mushy. Pull it when the edges bubble and top cheese is speckled gold, not brown.
- Leftover corned beef? This is its best use! The extra cooking time makes it even more tender.
Remember – great casseroles are about balance. Follow these tips, and you’ll nail it!

Common Questions About Corned Beef And Cabbage Casserole
I get asked about this recipe all the time – seems like everyone wants to make sure they’re doing it right! Here are the questions that pop up most often, along with my tried-and-true answers:
What’s the best way to reheat leftovers?
Oh honey, do yourself a favor and skip the microwave! For that just-baked texture, reheat your corned beef and cabbage casserole in a 350°F oven for about 15-20 minutes. Cover it with foil if you’re worried about drying out. The oven brings back that wonderful creaminess better than any microwave ever could.
Can I use canned corned beef instead?
You can, but I’ll be honest – it changes the flavor completely. Canned corned beef tends to be saltier and has a different texture. If it’s all you’ve got, rinse it well and pat dry before using. But trust me, leftover cooked corned beef or deli slices make this casserole shine!
How do I keep my cabbage from getting soggy?
This one’s simple – dry it like you mean it! After chopping, spread your cabbage on clean kitchen towels or paper towels and press gently. That extra minute makes all the difference between crisp-tender cabbage and mush. Also, don’t skip the foil during baking – it helps steam escape without drying out the whole dish.
What cheeses work besides Swiss?
Gruyère is my first choice swap – it melts beautifully and has that same nutty flavor. Sharp cheddar gives a bolder taste if that’s your thing. Just remember: always shred your own cheese! Those pre-shredded bags contain additives that prevent smooth melting. And whatever you do, don’t skip the mustard powder – it makes any cheese taste cheesier!

Serving Suggestions for Corned Beef And Cabbage Casserole
Now that you’ve made this glorious casserole, let’s talk about how to serve it up right! This dish is practically begging for some tasty sides to round out the meal. Here’s how I love to plate it up:
The Classic Combo: A big scoop of this cheesy goodness alongside some crusty Irish soda bread for mopping up every last bit of sauce. Add a simple green salad with tart vinaigrette to cut through the richness – baby arugula with lemon dressing is my go-to.

St. Patrick’s Day Feast: For holiday gatherings, I go all out with pickled vegetables (those spicy pickled carrots are amazing!), buttery boiled potatoes, and maybe even some Irish stout to wash it all down. The tangy pickles balance the casserole’s creaminess perfectly.
Weeknight Shortcut: When I’m feeling lazy (which happens more often than I’d like to admit), I just grab a bag of pre-washed salad greens and call it a meal. The casserole is hearty enough to stand alone!
Pro tip: Let the casserole sit for 5 minutes after baking – it makes serving cleaner slices much easier. And don’t be shy with extra cheese on top right before serving – that melty goodness is half the fun!
Storing and Reheating Corned Beef And Cabbage Casserole
Let’s talk leftovers – because let’s be real, this casserole is even better the next day! Here’s exactly how to store and reheat it so every bite tastes just as good as when it first came out of the oven.
Storing: Once cooled (but not room temperature – food safety first!), transfer your corned beef and cabbage casserole to an airtight container. It’ll keep beautifully in the fridge for 3-4 days. Want to freeze it? Portion into individual servings first – that way you can thaw exactly what you need. Frozen, it lasts about 2 months.
Reheating: Now listen close – resist the microwave temptation! To bring back that perfect creamy texture, reheat in a 350°F oven for 15-20 minutes. Cover with foil if you’re worried about drying out. For frozen portions, thaw overnight in the fridge first, then bake covered for 25-30 minutes. The oven works magic on reviving that crispy-cheesy top!

Pro tip: Sprinkle a little extra cheese on top before reheating – it melts into a fresh layer of deliciousness. And if the edges look dry, drizzle a tablespoon of milk over the top before popping it in the oven. Works every time!
Nutritional Information
Okay, let’s talk numbers – but remember, these are estimates that can vary based on your specific ingredients and portion sizes. Here’s the breakdown per serving (about 1/6th of the casserole):
- Calories: 420 – hearty but not outrageous for such a satisfying meal!
- Fat: 22g (12g saturated) – that’s the cheese and butter doing their delicious work
- Protein: 24g – thanks to all that wonderful corned beef
- Carbs: 32g (3g fiber) – mostly from the rice and cabbage
- Sodium: 890mg – corned beef brings the salt, so go easy if you’re watching intake
- Sugar: 6g – mostly natural from the milk and veggies
A little note from my kitchen to yours – these numbers can change based on the brands you use, how much cheese you add (no judgment if you go heavy!), or whether you swap ingredients. But honestly? Sometimes comfort food is just about comfort – and this casserole delivers that in spades!
