Cook chopped veggies in a steamer basket, microwave (with some liquid), or boil them in a pot filled with water until fork tender.
Run cold water over the cooked veggies to stop the cooking process (blanch).
Place cooked veggies inside a food processor and pulse a few times to coarsely chop. Run the food processor continuously for about a minute, until the veggies are smooth.
Add eggs, breadcrumbs, Parmesan cheese, and seasoning to the veggie mixture. Process the mixture with a few pulses until all the ingredients are even. If the veggie paste is too sticky, add additional bread crumbs.
Form the nuggets with a cookie scoop or with your hands and place them on a parchment-lined baking sheet.
Oven Method:
Preheat oven to 375F.
Bake veggie nuggets for about 15 minutes until golden brown.
Air Fryer Method:
Preheat air fryer for 5minutes at 400.
Cook veggie nuggets at 400F for about 8 minutes until golden brown. Flip them halfway through if your air fryer basket does not have a tray/rack.
Pan Frying Method:
Heat up a large non-stick pan over medium-high heat. Place about 2 tablespoons of oil at the bottom of the pan and heat it for about a minute. Distribute hot oil around the pan.
Place veggie nuggets in the hot oil, making sure to not crowd the pan, and cook them for about 4 minutes per side, until golden brown and crispy. Remove from pan onto a plate and cook the next batch.
Notes
If you overcook your veggies, your nuggets will feel "wet." It's best to undercook veggies to a crisp texture. They will finish cooking in the oven/pan/air fryer.Gluten-Free: Make these veggies gluten-free by using gluten-free bread crumbs or substituting the bread crumbs with instant/quick-cooking oats, the same amount.
