Baked Beetroot Burger with Lentils
The Lentil and Beetroot Burger is a delicious vegetarian option that even meat lovers will enjoy! The baked or air-fried patties are packed with nutrients and served with a citrus-dill mayo, avocado, tomato, and lettuce.

This beetroot burger is a brilliant way to introduce kids to lentils and beets without them even noticing! A hearty blend of lentils, beetroot, chickpeas, onion, garlic, and smoky Spanish paprika creates a flavourful, earthy patty. Paired with a creamy citrus-dill mayo, it strikes the perfect balance of tang and smoothness, an ideal vegetarian burger for the whole family!
The Patty

I recommend blending the onion and garlic first to avoid large chunks in the patties. The rest of the ingredients don’t need to be perfectly smooth; pulse the mixture until you’re happy with the texture, but stop well before it turns into a paste. You want some whole lentils peeking through for a bit of texture and visual appeal.
Unlike a typical meat patty that you can press together with your hands, this beetroot burger mixture is on the loose side. Use a spoon to shape the patties directly onto your oven mat or parchment paper; this actually makes it easier to customize the size and thickness. You can even shape them into hearts for Valentine’s Day!
Baking or Air Frying
Whether you bake or air-fry the patties, a non-stick mat or parchment paper is your best friend here. If using an air fryer, opt for perforated parchment to allow proper air circulation. Once the patties come out, let them rest for a minute before lifting them with a spatula; they firm up quickly as they cool.

Beetroot
You can easily roast your beetroot by wrapping it in aluminum foil and air frying it at 200°C (400°F) for about 30 minutes, or roasting it in the oven for about an hour. Pre-cooked or vacuum-packed beetroot works perfectly well too and is a great time-saver.
Baby Led Weaning
The pink patty is an excellent option for toddlers because:
- Nutrient-Packed: Lentils and chickpeas provide protein and iron, while beets add fibre, vitamins, and natural sweetness.
- Soft Texture: The patties are baked, making them tender and easy for little ones to chew.
- Wholesome Ingredients: Served with avocado and tomato, it’s a well-balanced meal.
- Customizable: It can be served as a mini patty, crumbled over rice, or even made into bite-sized nuggets for little hands to grab!
