These garlic Parmesan pierogies bake Mrs. T's frozen pierogies until golden and crispy then toss them in a warm garlic Parmesan butter sauce for an easy side dish or appetizer ready in 25 minutes.
Next, spread the frozen Mrs. T’s Pierogies into an even layer on a 13 x 9-inch baking dish or baking sheet. Lightly spray the tops with olive oil.
Bake for 16–18 minutes, flipping the pierogies halfway through so both sides become evenly golden and crispy.
Meanwhile, melt the butter in a large mixing bowl. Add the garlic, Parmesan cheese, and remaining seasonings, then stir until everything is well combined.
As soon as the pierogies come out of the oven, transfer them directly to the bowl with the garlic Parmesan butter mixture while they’re still hot. Gently toss until each pierogy is evenly coated.
Finally, sprinkle with additional Parmesan cheese before serving.
