These baked mushroom and red lentil meatballs make an easy, budget-friendly, crowd-pleasing meal. Nutrient-dense, flavorful, and packed with protein and fiber, they require just a few simple, inexpensive pantry staples. They are oil-free, dairy-free, optionally gluten-free, and perfect for enjoying with spaghetti, in a sub, and more!
In a saucepan with a lid over medium-high heat, bring water to a boil.
Once water is boiling, add the lentils, bring heat to low, and cover with a lid. Cook lentils for 15 to 20 minutes, or until water is absorbed and lentils are soft.
Remove the lentils from heat and let cool.
In a nonstick pan over medium-high heat, add chopped mushrooms and cook until mushrooms lose their juices. Let mushrooms cool.
Add kale, onion, garlic, mushrooms, and lentils to a food processor. Pulse on low until all items are mixed through.
Transfer the lentil mixture to a bowl and add the dried basil and then add the bread crumbs slowly. You only need enough to get the mixture sticky enough to form balls.
Place mixture in the refrigerator for 10 minutes.
While the mixture is cooling, preheat the oven to 425 degrees F.
Remove mixture from refrigerator and form the vegan meatballs. You want them to be about 1 to 2 inches.
Place on a baking sheet lined with a silicone mat or parchment paper, place in the oven and cook for 10 minutes. After 10 minutes, flip and cook for 5 more minutes.
Notes
Raw vs. cooked aromatics: It can increase the depth of flavor to lightly sauté the chopped onion and garlic (until lightly browned) before adding it to the lentil-mushroom mixture.
Don’t over-process the mixture: These lentil mushroom meatballs are best when they still have a bit of texture rather than completely pureed. The latter will be hard to form into balls and have a very different texture/ mouthfeel.
For crispier meatballs: Lightly spray the meatballs with some cooking spray or oil to encourage browning and a crisp exterior.
If the mixture is too wet: You can add slightly more breadcrumbs (or oats). I recommend waiting until after the refrigerator chilling time, though, as this will give them a chance to soak up the excess liquid.
Drain the lentils if needed: If you find excess liquid in the pan once the lentils are cooked, drain it well to prevent mushy meatballs.
Wet your hands before rolling: This can help to prevent the red lentil-mushroom mixture from sticking to them.
