Lamb Casserole with New Potatoes

What is it?

Lamb pieces sit in a rich casserole sauce with baby new potatoes, ready from frozen. In a tray format, it’s a straightforward oven or microwave meal built around chunks of lamb, gravy-style sauce, and potatoes that hold their shape rather than melting away. COOK uses the same freezer-first approach across its range, with this one leaning into a classic British casserole structure instead of pasta, rice, or mash. Small vegetables may be included in the sauce, depending on the batch.
