How long does Dolly Parton's casserole take to cook?

About 2 hours and 20 minutes total. Prep is super quick, maybe 20 minutes, then it bakes for a solid 2 hours until those potatoes are fork-tender and the cheese (if you add it!) is all bubbly and golden. It's a low and slow kind of dish, but totally worth the wait.

Can I use different vegetables in this casserole?

Absolutely! I've swapped the bell pepper for frozen mixed veggies when I was in a pinch, and it still tasted great. Just make sure they're thinly sliced or small enough to cook through. You could even add some corn or peas. My husband doesn't usually like bell peppers, so sometimes I'll use carrots instead.

How do I store leftovers or make this ahead?

Leftovers are amazing, honestly, the flavors develop overnight! Just cover it tightly and keep it in the fridge for up to 3 days. For making ahead, assemble the whole thing, cover it, and refrigerate for up to 24 hours before baking. Add about 15-20 minutes to the bake time if baking from cold.

Why are my potatoes still hard after baking?

Oh, I've been there! The thing is, those potatoes need time. Make sure they're sliced really thin, like 1/8 inch. And don't skimp on the baking time – two hours covered is usually the sweet spot. If they're still firm, just pop it back in for another 20-30 minutes, covered. Mine didn't look perfect the first time either, but patience is key!

What do you serve with Dolly Parton's casserole?

This casserole is pretty hearty on its own, but I love serving it with a simple green salad with a bright and citrusy vinaigrette to cut through the richness. Sometimes I'll do some crusty bread for soaking up all those delicious juices. It's a full meal, but a little freshness always makes it better!
