What Ingredients Do I Need?

Don’t be intimidated by this ingredient list! You can find everything you need at Hy-Vee or your local grocery store.

Bacon – This is the #1 most important ingredient because….BACON. We recommend using Burgers’ Smokehouse Bacon, either Uncured Country Bacon or Hickory Smoked.

Once you try Burgers’, you can never go back. The difference is all in their dry cure method…

Find Burgers’ Smokehouse Bacon at your local Hy-Vee or find a store near you that carries it.

Gruyere Cheese – This is perhaps the second most important ingredient, turning what could be a boring casserole into something gourmet! Gruyere is a hard light yellow Swiss that’s known as a mild-tasting melting cheese. It adds savoriness without overshadowing the other ingredients. I bought one 6 ounce block and shredded it by hand. It just took a minute or so.

Note: You can substitute your favorite shredded cheese, if you don’t have Gruyere. Cheddar cheese or Colby jack would work well.

Shredded Parmesan cheese – Provides another layer of flavor.

Roasted red peppers – Adds color and savoriness. Find a jar in the pickle aisle.

Kale – Adds amazing color and nutrition. You can’t really taste it, though. You can substitute baby spinach instead.

Yellow onion

Fresh or frozen hash browns – Make sure they are thawed first.

Milk – Your choice of what kind but I used 2%.

Large eggs

Salt and pepper, red pepper flakes, and garlic cloves – Good seasoning along the way is essential to this recipe.
