Ingredients & Substitutions
I love using portobello mushrooms because they have that meaty texture and rich flavor. You can also mix in other veggies like spinach or bell peppers for added nutrients. If you don't have quinoa, brown rice works great too!
Tips & Notes
- •I keep my quinoa cooking in a big batch so I can use it throughout the week in different recipes!
- •For an extra kick, try adding some chopped jalapeños to the filling.
Recipe Variations
- •Sometimes I’ll swap out the portobello for large zucchini slices for a lighter option.
- •You can also try adding a tablespoon of your favorite hot sauce to the filling for some spice.
Storage & Freezing
These burgers are best enjoyed fresh, but you can store leftovers in an airtight container in the fridge for up to 3 days. Just reheat them in the oven or on a skillet until warmed through.
Frequently Asked Questions
Can I make these ahead of time?
Absolutely! You can prepare the quinoa mixture and stuff the mushrooms a day in advance, then just bake them when you're ready to eat.
What can I use instead of breadcrumbs?
You could use crushed oats or ground nuts if you want a gluten-free option.
