We make potato fritters throughout the year, but especially in the fall and winter when we have comforting mashed potatoes on repeat.
The added veggies also make the leftover mashed potatoes go further, so we can turn a few cups of mashed potatoes into a full meal for the whole family that's fun to eat, too!
🧄 Very useful ingredient notes
- Leftover mashed potatoes - Cold, leftover mashed potatoes are the base for these! Of course, if you want this to be vegan, use vegan mashed potatoes.
- Nutritional yeast - adds a cheesy flavor, kinda like baked potato. The nooch also acts to absorb some of the liquid so the fritters stay together.
📋 Substitutions and variations
Here are some suitable substitutions for the ingredients in this recipe:
- Leftover mashed potatoes - instead of leftover mashed potatoes, you could use pre-cooked or pre-steamed potatoes that have been mashed well.
- Frozen broccoli and corn - use other frozen or fresh diced vegetables instead of the broccoli and corn. Frozen mixed vegetables work well. You could also use frozen California medley (cauliflower, broccoli, and carrot). Whatever you use, be sure to dice it up, if you're using bigger veggies.
Switch things up with these variation ideas!
- Spicy - add cayenne pepper, chili pepper flakes or, use cajun salt, like Tony Chachere's, instead of sea salt.
- Tater Tots - shape them into tater tots for a fun variation, which is especially popular with kiddos
🔪 Instructions
Here's the step-by-step instructions for how to make these potato, broccoli & corn fritters with leftover mashed potatoes!
- Cut broccoli florets into small pieces. It's helpful to heat them for 2 minutes in the microwave first, just to thaw them a little bit. They are easier to cut that way. They will cook in the oven/air fryer, so microwaving them is purely to make them easier to chop. If you're using fresh broccoli instead of frozen, there's no need to microwave it first.
- Add all ingredients (potatoes, broccoli, corn, nutritional yeast, green onion, salt, garlic, onion, black pepper and onion powder to a large bowl.
- Stir everything together, so all the seasonings are well-incorporated.
- This is what the mixture should look like. Thick and well-mixed.
- Shape into thin patties or discs.
Oven Instructions: Line a baking sheet with parchment paper. Add fritters in a single layer. Do not overlap them. Use two sheet pans, if needed. Bake at 425°F for 40-50 minutes, until a golden-brown crust has formed on the outside.
Air Fryer Instructions: Line your air fryer basket with parchment paper (skip this step if your air fryer basket is TRULY non-stick). Add fritters in a single layer. Do not overlap them. You'll likely have to make a few batches. Air-fry at 400°F for 20-22 minutes, until a golden-brown crust has formed on the outside.
- Serve with your favorite dipping sauce, such as BBQ sauce, ketchup, mustard or vegan ranch dressing.
Expert tips
- Don't be tempted to bake these without using parchment paper or a silicone baking mat. They'll stick like crazy!
- If your air fryer is truly non-stick, you can probably get away without lining it. But, I've tried that with my metal air fryer basket and it was a bugger to clean! Don't make my mistake. Just line it and you'll save yourself the headache.
- Do you have any leftover veggies hanging out in the fridge? Those might be PERFECT for mixing into these potato fritters! Just be sure to dice them up into small pieces, so you can form the patties.
🍳 Equipment
- Air Fryer - Making these in an air fryer will be quicker, if you're making a small batch. If you're doing a lot, then the oven may be a better option. An air fryer or convection oven with a fan will brown them up quickly and help them get a little crispy without drying them out too much. I use the Ninja Air Fryer that saves counter space by flipping up when not in use. I can cook about 9 of these patties/pancakes at one time in there.
