Pumpkin Burgers

What is the difference between these burgers and the moulded ones? Well, if you want a finished burger with a precise shape (round, heart-shaped, bigger/smaller, ...) then the hand-formed burgers give a more defined result, but this takes more time because you actually have to shape the burgers one by one. If instead you prefer a quicker preparation, once the mixture is ready you can put it into a container, as shown in the moulded pumpkin burgers recipe, and refrigerate it; then when you need to cook the burgers, just take the mixture from the mould and cut the slices you need, where each slice will be a burger.

1. Ingredients

Dough

The pumpkin in the table is already roasted and cleaned: 600 g is the cooked flesh that goes into the mix, not the whole raw pumpkin. To get it you need about 800 g of raw pumpkin already stripped of skin and seeds (which loses more water in the oven). See the Technical Notes for why.

2. Method

1. Peel the pumpkin, remove the seeds and cut into pieces of about 2-3 cm. You need about 800 g of raw cleaned pumpkin to obtain the 600 g of roasted flesh for the mix. Cook it in one of two ways:
   • In the oven: lay the pieces on a lined tray, not overlapping, with a drizzle of oil; bake in a static oven at 180 °C for 30-40 minutes (up to 45-50 if the pieces are large), until soft and lightly caramelised.
   • In the microwave: place the pieces, not overlapping, in a microwave-safe container with a little water in the bottom (for example a glass baking dish covered with a plate or a microwave-safe plastic dome). Cook at full power for 8-10 minutes, checking halfway and turning the pieces, until soft. These are indicative times: judge by how soft the pumpkin is at the halfway point to see whether it needs more or less time.
   Drain off any residual water, let it cool, then mash to a purée (it will be dried in the pan together with the beans, see below).

   

   

   

2. Drain and dry the 250 g cooked cannellini beans well and roughly mash them. They are the binder: they will be added to the pan together with the pumpkin, where they finish breaking down and drying out.
3. Finely chop the 60 g onion and the 60 g carrots and soften them in a pan with a little oil until soft and dry. Towards the end add the pumpkin purée and the mashed beans and continue a few minutes, stirring: the beans break down and, together with the pumpkin, lose the excess water and start to bind. Turn off the heat and let cool slightly.

   

   

   

4. Make the mix.
5. Transfer the pumpkin, bean, onion and carrot mixture to a bowl, add the 6 g fine salt, paprika, chopped rosemary, pepper and optionally the nutmeg (optional, to add together with or instead of the paprika), and the 20 g olive oil. Add the 40 g breadcrumbs a spoon at a time, until you get a mixture that holds its shape in your hands. If it stays sticky, add more breadcrumbs; if too dry, a drizzle of oil. As a rule, it is best not to use more breadcrumbs or oil than necessary.

   

   

6. Shape and rest.
7. Let the mix rest 5-10 minutes (the breadcrumbs absorb the moisture). Shape the burgers by hand (about 100 g each, 1.5-2 cm thick) and coat both sides in breadcrumbs. A 30-minute rest in the fridge before cooking makes them firmer and easier to turn (recommended with a soft mix like this one).

   

8. Cook — choose a method.
9. Pan: heat a little olive oil over medium heat and cook the burgers 3-4 minutes per side until golden and crisp. Turn gently with a spatula — they are soft.
10. Oven: fan oven at 190 °C (or static at 200 °C). Lay the burgers on a lined tray, drizzle oil on top, and bake 16-20 minutes, turning halfway, until golden.
11. Air fryer: preheat to 180-200 °C. Place the burgers in the basket without overlapping and cook 15-20 minutes until the surface is golden and crisp, turning halfway.
12. Serve hot, on their own or in a bun with salad and sauce.

    

    

3. Storage

• Refrigerator: the raw, shaped and coated burgers keep 2-3 days in the fridge, ready to cook; cooked ones 2 days.
• Freezer: freeze the raw, coated burgers laid out on a tray, then transfer to a bag once hard (so they keep their shape). Thaw in the fridge and cook as preferred, or cook from frozen adding a few minutes.

4. Technical Notes

• Raw or cooked pumpkin? In the table the 600 g is already-roasted flesh, i.e. what actually goes into the mix. Whole raw pumpkin weighs a lot more: with skin and seeds removed (about 15-20%) and the water lost in the oven, you need about 800 g of raw cleaned pumpkin to reach the 600 g cooked. The cooked weight was chosen as the reference because that is what matters for the burger's texture.
• Why roast the pumpkin rather than boil it: pumpkin is about 90% water. Boiling makes it absorb even more water, giving a soft mix that falls apart. Roasting it in the oven dries it and concentrates the flavour, giving a drier, tastier mix. If it is still moist after cooking, you can dry it by adding it to the carrot and onion sauté towards the end. The underlying principle: better to remove water than to add binder — every gram of evaporated water is breadcrumbs saved and a tastier burger.
• Why you need a binder: pumpkin does not bind on its own, so you need an ingredient to hold the mix together. As a binder, beans and potatoes are equivalent: both, cooked and mashed, compact the mixture and, once cold, hold it together without any egg or cheese. In this recipe we use already-cooked cannellini beans for convenience and speed — added to the pan they break down and dry out, becoming an excellent binder despite having less starch than potatoes. Potatoes give an equally good result, but must be boiled first (20-30 minutes in their skins, then peeled and mashed): see the variants.
• Moisture is the enemy of the binder: this holds for all legumes. Drain and dry them well, because the canning liquid makes the mix soft, and keep a moisture absorber handy (breadcrumbs, or for chickpeas even chickpea flour) to fine-tune the texture. In any case, cooking in the pan solves most of the problem, evaporating the residual water.
• Why breadcrumbs a spoon at a time: they are the final moisture regulator. Adding them gradually lets you stop as soon as the mix holds its shape, without drying it out. A 5-10 minute rest gives them time to absorb the residual water before you shape the burgers.
• Why the fridge rest before cooking: the cold firms the mix and reduces the risk of the burgers splitting during cooking. With a soft mix like this one (pumpkin + beans, no egg) it helps a lot, especially for pan cooking.
• The spices: paprika, finely chopped rosemary, nutmeg and black pepper are what give the burger its aromatic profile. All to taste: start with a little and adjust. Paprika (sweet or smoked) and nutmeg pair especially well with pumpkin.

Variants — changing the binder

• With potatoes: potatoes replace the beans 1:1 by weight (250 g). Unlike the beans they must be boiled first: 20-30 minutes in their skins, then peeled while hot and mashed. They bind beautifully thanks to their starch and give a slightly drier mix with a more neutral flavour. Add them to the mix together with the sautéed vegetables (no need to pass them through the pan like the beans).
• With borlotti beans: same 1:1 proportion as the cannellini, already cooked and well drained, added to the pan like the cannellini. Very similar to cannellini in result and creaminess, with a slightly bolder flavour.
• With chickpeas: same 1:1 proportion, already cooked and well drained. Chickpeas are drier and more granular (less risk of a soft mix) and bring a bolder, roasted, falafel-like flavour. Unique advantage: they can be bound with chickpea flour (1-2 tablespoons), the same ingredient, without altering the flavour — useful if the mix stays soft.
• Rule for all legumes: moisture is the enemy of binding. Drain and dry the legumes very well (the governing liquid makes the mix soft) and keep a moisture absorber ready (breadcrumbs or, for chickpeas, chickpea flour) to adjust the raw consistency.
