Scalloped Potatoes with Roasted Cherry Tomatoes
A comforting casserole that transforms boxed scalloped potatoes into something special with the addition of roasted cherry tomatoes. The creamy, cheesy potato base gets topped with caramelized tomatoes that have been roasted until their edges are golden and their flavors concentrated. Fresh thyme and Parmesan cheese add aromatic depth, while a sprinkle of fresh parsley brightens the finished dish. Perfect for busy weeknight dinners or as a hearty side dish for family gatherings when you want maximum flavor with minimal prep work.

FAQ
Can I use fresh potatoes instead of the boxed mix?
Yes, but you'll need to slice 2-3 pounds of potatoes and make a cheese sauce with butter, flour, milk and seasonings. Baking time will increase significantly.
What if my tomatoes aren't browning enough?
Move the tomato pan to a higher rack or broil for 2-3 minutes at the end, watching carefully to prevent burning.
How long will leftovers keep in the refrigerator?
Store covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or the whole dish in a 350°F oven.
