Can I use a different cut of meat?

Absolutely. Ground beef works for speed and even texture, but you can use diced beef that you braise slowly first. The dish still holds its character. If you use a tougher cut, cook it low and slow until tender before assembling.

What if I want a lighter version?

Swap whole milk and heavy cream for a mix of low-fat milk and low-sodium broth. Use less cheese or choose a lower-fat cheese. You will keep the comfort while dialing down richness.

Can I make this in a slow cooker?

Yes. Brown the beef and sauté aromatics first, then layer potatoes and beef in the slow cooker, add the sauce, and cook on low for 6 to 7 hours. Check after six hours for tenderness. Finish under the broiler with cheese for a crisp top.

How thin should the potato slices be?

Aim for about 1/8 inch thickness. Even thin slices ensure they cook through during the bake and meld into a cohesive texture.

Can I add vegetables?

You may fold in thinly sliced mushrooms, bell peppers, or a handful of spinach. Keep in mind added vegetables may change moisture and cook times. Sauté firmer vegetables first to remove excess moisture.

Instructions

Preheat your oven to 350°F (175°C).
In a cast iron skillet over medium heat, sauté diced onion in olive oil until translucent.
Add minced garlic and cook until fragrant, then stir in ground beef and seasonings. Cook until browned.
In a mixing bowl, combine sliced potatoes with melted butter and seasonings. Toss gently so each slice gets a light coating.
Layer half of the potatoes at the bottom of a baking dish, followed by the beef mixture and the remaining potatoes.
Whisk together whole milk, heavy cream, flour, salt, mustard powder, and parsley for the creamy sauce; pour over the layered casserole.
Top with an even layer of shredded cheeses.
Cover with foil and bake for 45 minutes; remove the foil and bake for an additional 15 minutes until golden brown.
Let cool slightly before serving and garnish with chopped fresh parsley.

Notes

For a lighter flavor, swap some milk with low-sodium broth. Use Yukon Gold potatoes for a creamier texture. Adjust cheese quantities as preferred.
