Preheat oven – 350°F (175°C).
Prepare the chard – Wash Swiss chard, leaving slightly damp. Chop stems and leaves separately.
Cook vegetables – Heat oil or vegan butter in a 10-inch oven-proof pan over medium heat. Sauté onion, chard stems, and mushrooms 5–6 minutes until softened. Add garlic and cook 1 minute. Add chard leaves, season lightly, and cook until wilted.
Mix eggs or plant base – In a bowl, whisk eggs with milk and cheese (or plant-based alternatives). Stir in the chard and mushroom mixture until well combined.
Bake – Pour mixture back into the pan and transfer to oven. Bake 50 minutes until puffed and golden.
For mini frittatas: Spoon mixture into greased muffin tins and bake 25–30 minutes.
Serve – Let cool slightly before slicing. Garnish with extra herbs if desired.
