Questions

Can I make Tennessee Onions dairy-free?

Not cleanly. Here the dairy (4 tbsp unsalted butter, cut into pats, 1 cup sharp cheddar cheese, shredded, 1 cup Monterey Jack cheese, shredded, 1/2 cup Parmesan cheese, grated) is the backbone of the dish, and plant-based substitutes change both its texture and its flavor. If you need strictly dairy-free, start from the dairy-free side collection instead.

How long does Tennessee Onions keep?

Refrigerate leftovers within two hours and eat them within three days. Reheat covered in a 300 F oven until warmed through.

Can I halve or double Tennessee Onions?

Yes. As written it serves 6. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Doubled, split it across two pans and rotate them halfway; one crowded pan bakes unevenly.
