Hearty Tomato & Gnocchi Bake

This hearty, flavour-packed one-pan bake is a dream for busy weeknights, comforting, nutritious, and minimal on cleanup. Made with soft potato gnocchi, protein-rich green lentils, and iron-packed spinach, it’s a balanced plant-based meal the whole family will love. Plus, it reheats beautifully for quick, wholesome lunches.

The slow-simmered cherry tomato sauce is rich in antioxidants like lycopene and naturally sweetened with maple syrup and balsamic vinegar for a deep, umami-rich flavour. Lentils add a boost of plant-based protein and gut-friendly fibre, while spinach brings iron, folate, and vitamin C. Topped with fresh basil and optional chili flakes for warmth, this vibrant bake is a fibre-rich, freezer-friendly, family favourite, perfect for batch cooking, meat-free Mondays, or nourishing comfort food you’ll turn to again and again.
