Green Burgers with Spinach, Cheddar, and Parmesan Recipe
Introduction
These vibrant green burgers are a delicious vegetarian alternative that combines spinach, cheese, and fragrant nutmeg for a flavorful twist. They’re easy to make, juicy, and perfect served in crusty rolls with fresh tomatoes and your favorite relish.

Ingredients
- 2 tbsp olive oil
- 2 onions, finely chopped
- 250g bag spinach
- 5 slices white bread, blitzed into breadcrumbs (or 150g dried breadcrumbs)
- Good grating of fresh nutmeg
- 100g mature cheddar, grated
- 40g Parmesan, finely grated
- 1-2 large eggs, beaten
- 3 tbsp plain flour
- 6 crusty bread rolls
- 4 ripe, juicy tomatoes, thickly sliced
- Good-quality ketchup or other relish
- Sweet potato fries (optional)
Instructions
- Step 1: Heat half the olive oil in a frying pan and gently fry the finely chopped onions for about 10 minutes until pale and soft. Remove from heat and let cool slightly.
- Step 2: Finely chop the spinach using a food processor and transfer to a large bowl. Add the cooled onions, breadcrumbs, nutmeg, mature cheddar, and Parmesan. Mash the mixture together until combined.
- Step 3: Gradually add the beaten eggs, a little at a time, mixing until the mixture holds together well. You may not need all the egg. Divide the mixture into eight portions and shape each into a thick burger patty.
- Step 4: Place the plain flour in a shallow bowl, season it well, and dip each burger patty into the flour to coat thoroughly. You can store the burgers in a plastic container between layers of baking parchment if not cooking immediately; chill or freeze as needed.
- Step 5: Heat the remaining olive oil in the frying pan and cook the burgers for about 5 minutes on each side, until they are golden brown and cooked through.
- Step 6: Serve the green burgers in crusty bread rolls with thick slices of tomato and a generous drizzle of ketchup or relish. Sweet potato fries make a perfect side if desired.
Tips & Variations
- Flouring your hands before shaping the patties helps prevent the mixture from sticking to your fingers.
- For a spicier version, add a pinch of chili flakes or smoked paprika to the burger mixture.
- Swap mature cheddar for a sharp or smoked variety for a different flavor profile.
- If you prefer, you can bake the burgers at 180°C (350°F) for 15-20 minutes instead of frying.
Storage
Store uncooked burgers in an airtight container between layers of baking parchment in the fridge for up to 2 days or freeze for up to 1 month. To reheat, cook from frozen in a frying pan or oven until heated through and browned. Cooked burgers keep well in the fridge for 2 days and are best reheated gently in a pan or oven to maintain texture.

FAQs
Can I make these burgers vegan?

Can I prepare the burger mixture ahead of time?
Yes, you can prepare the mixture, shape the patties, and store them in the fridge for 1-2 days or freeze them. This makes it easy to cook fresh burgers whenever you want.

Ingredients
Burger Patties
- 2 tbsp olive oil
- 2 onions, finely chopped
- 250g bag spinach
- 5 slices white bread, blitzed into breadcrumbs (or 150g dried breadcrumbs)
- Good grating of fresh nutmeg
- 100g mature cheddar, grated
- 40g Parmesan, finely grated
- 1–2 large eggs, beaten
- 3 tbsp plain flour (for coating, seasoned with salt and pepper)
To Serve
- 6 crusty bread rolls
- 4 ripe, juicy tomatoes, thickly sliced
- Good-quality ketchup or other relish
- Sweet potato fries (optional)
Instructions
- Cook Onions: Heat half the olive oil in a frying pan over medium heat and gently fry the finely chopped onions for about 10 minutes until they become pale and soft. Once cooked, remove from heat and allow them to cool slightly.
- Prepare Spinach and Mix Ingredients: Finely chop the spinach using a food processor until well chopped and transfer it to a mixing bowl. Add the cooled onions, breadcrumbs, a grating of fresh nutmeg, grated mature cheddar, and finely grated Parmesan. Mash all these ingredients together thoroughly.
- Add Eggs: Gradually add the beaten eggs to the mixture, bit by bit, mixing in between, until the mixture holds together well. You may not need to use all the egg. Once ready, divide the mixture into eight equal portions and shape each into a fat burger patty. Flour your hands lightly to prevent sticking if necessary.
- Coat Patties with Flour: Place the plain flour in a shallow bowl, season well with salt and pepper, and dip each burger patty into the flour to coat evenly. Store the coated patties in a plastic container with layers of baking parchment in between each, then chill until ready to cook or freeze for later use.
- Cook Burgers: Heat the remaining olive oil in a frying pan over medium heat. Fry the patties for about 5 minutes on each side, or until browned all over and cooked through.
- Assemble and Serve: Slice the crusty bread rolls in half and place a cooked green burger patty inside each. Add a couple of thick tomato slices and a generous dollop of good-quality ketchup or your favorite relish. Serve immediately, optionally alongside sweet potato fries for a complete meal.
Notes
- Flouring your hands before shaping the patties helps prevent the mixture from sticking.
- The number of eggs needed may vary depending on the moisture content of the spinach and other ingredients; add gradually to reach the right consistency.
- These patties can be made in advance and frozen; just cook straight from frozen, adding a few extra minutes if needed.
- Sweet potato fries are an optional but delicious side to complement the green burgers.
- For a gluten-free version, substitute the white bread and plain flour with gluten-free alternatives.
