As a child growing up in a home where hearty Italian cooking ruled the table, I quickly learned that comfort food didn’t always need to come with a side of guilt. One of my grandmother’s clever ways of turning garden abundance into something truly satisfying was through baked dishes. Zucchini, often too plentiful in the summer, became the star of many casseroles. This Ground Beef Zucchini Bake is one of those treasures. With lean ground beef, tender zucchini, and melty cheese, it’s both nourishing and soul-warming—yet light enough to fit into a low carb lifestyle.
