Don’t stress about equipment for this one—a basic oven and a baking dish are all you need. I usually throw in a side salad or some crusty bread to round out the meal. Sometimes, I swap in different veggies depending on what’s in the fridge—carrots, spinach, or even corn can work, though I haven’t tested all combos thoroughly. If you want it a little spicier, a pinch of red pepper flakes can add a nice kick without overpowering.

FAQ

Can I freeze this casserole? I haven’t tried freezing it myself, but it should freeze and reheat reasonably well if wrapped tightly.

What’s a good side dish? A light green salad or steamed broccoli complements the richness nicely.

Can I use ground chicken instead? Ground chicken could work, though the texture might be a bit different.
