Ingredients You’ll Need
Gather your troops! Here’s what you’ll need to make this magic happen:
- Cooked Corned Beef: About 2-3 cups, shredded or diced. The star of our show, obviously. Leftovers are perfect here!
- Potatoes: About 4-5 medium-sized, peeled and diced. Or, if you’re feeling fancy (or super lazy), a bag of frozen diced potatoes works too. No judgment here!
- Onion: 1 medium, chopped. Don’t cry, it’s worth it.
- Butter: 2 tablespoons. Because everything is better with butter, right?
- All-Purpose Flour: 2 tablespoons. Our thickening buddy for a luscious sauce.
- Milk: 2 cups. Whole milk gives it that extra ‘oomph,’ but whatever you have will do.
- Cheddar Cheese: 1.5 cups, shredded. The more, the merrier, IMO.
- Dijon Mustard: 1 tablespoon. Just a little kick to make things interesting.
- Salt & Pepper: To taste. Be brave, season well!
- Optional: Fresh Parsley: For garnish. Makes it look like you tried harder than you did.
Step-by-Step Instructions
Alright, let’s get cooking! Follow these super simple steps:
- Prep the Spuds: First things first, get those potatoes ready. Boil ’em until they’re fork-tender, then drain. If you used frozen, just follow the package directions for cooking or skip to the next step if they’re pre-cooked. Preheat your oven to 375°F (190°C).
- Sauté the Aromatics: In a large skillet, melt the butter over medium heat. Toss in the chopped onion and cook until it’s soft and translucent—usually about 5 minutes. Resist the urge to snack on them.
- Make a Roux (Don’t Panic!): Sprinkle the flour over the softened onions. Stir constantly for about a minute; you’re making a roux, fancy pants! This is what thickens our sauce, so don’t skip it.
- Whisk in Milk & Season: Gradually whisk in the milk, making sure there are no lumps. Bring it to a gentle simmer, stirring often until it thickens up a bit. Take it off the heat and stir in the Dijon mustard, salt, and pepper. Give it a taste test – adjust seasoning as needed!
- Cheese Time: Now for the good stuff! Stir in about 1 cup of the shredded cheddar cheese until it’s all melted and glorious. Reserve the rest for the top.
- Combine Everything: In a large mixing bowl, gently combine the cooked corned beef, the tender potatoes, and that dreamy cheese sauce. Mix it up without smashing everything to smithereens.
- Bake It Up: Pour the mixture into a 9×13 inch baking dish (or similar size). Sprinkle the remaining cheese evenly over the top. Bake in your preheated oven at 375°F (190°C) for about 25-30 minutes, or until it’s bubbly and the cheese on top is golden brown and irresistible.
- Rest & Serve: Let it rest for 5-10 minutes before serving. This lets it set up nicely. Garnish with parsley if you’re feeling extra fancy. Dig in!
Common Mistakes to Avoid
Nobody’s perfect, but we can avoid these common casserole blunders:
- Not Preheating the Oven: Rookie mistake! Your casserole won’t cook evenly, and you’ll end up with lukewarm patches. Always preheat, folks.
- Overcooking the Potatoes: Soggy potatoes are a sad affair. Boil them just until fork-tender, not mushy. You want some structure there!
- Skimping on Cheese: This isn’t the time for a diet. Cheese is flavor, cheese is life. Go big or go home (but really, just go big).
- Forgetting to Season: Bland food is a crime. Taste your sauce, adjust your salt and pepper. Be bold! You got this.
Alternatives & Substitutions
Feeling creative? Or just missing an ingredient? No worries, we’ve got options:
- Potatoes: No fresh potatoes? Canned diced potatoes or even leftover mashed potatoes (mixed into the sauce before baking) can work in a pinch. Just adjust the cooking time slightly.
- Cheese: Cheddar is classic, but Swiss, Gruyère, or even a Monterey Jack would be fabulous. Mix and match to your cheesy heart’s content!
- Corned Beef: Leftover roast beef or even cooked ground beef could sub in, but then it wouldn’t be a corned beef casserole, would it? Just sayin’.
- Spice It Up: A pinch of red pepper flakes in the sauce adds a nice kick if you’re feeling feisty.
FAQ (Frequently Asked Questions)
Got questions? I’ve got answers (and probably some sassy commentary):
- Can I use store-bought shredded cheese? Of course! But if you shred your own, it often melts a bit smoother. Just a little chef’s secret, FYI.
- What if I don’t have Dijon mustard? A little bit of dry mustard powder (about 1/2 teaspoon) can work, or just skip it. It adds a lovely tang, though!
- Can I assemble this ahead of time? Absolutely! Cover it and refrigerate for up to 24 hours. You might need to add an extra 10-15 minutes to the baking time if it’s going in cold.
- Is this freezer-friendly? Mostly! It freezes well for about 2-3 months. Thaw in the fridge overnight before reheating. The potatoes might get a *tiny* bit softer, but still delicious.
- My sauce is too thin/thick! Help! Too thin? Simmer a bit longer. Too thick? Whisk in a splash more milk until it reaches your desired consistency. You’re the boss!
