Table of Contents
Ingredients
I am highlighting just the ones that need further explanation. The complete list is in the recipe card below.
- Mushrooms – I love adding mushrooms to ground meat. Not only is it a great way to amp up the nutritional value (it’s an excellent source of vitamin D, potassium, and selenium), but it also helps bulk up the volume, making my pound of meat go a long way. And it enhances the umami flavor, which equals deliciousness!
- Quinoa – Known as a superfood that adds a slightly nutty flavor. An excellent source of protein, fiber, and various vitamins and minerals.
- Spinach – Adds a mild, earthy flavor. Spinach helps keep the meatballs moist and tender. Its high water content contributes to a softer texture, preventing the meatballs from drying out during baking.
- Rolled Oats – Helps bind the meatball mixture together, giving the meatballs a firm texture that holds up well during baking.
Substitutions
If you need to adjust the recipe to suit different dietary preferences or to use ingredients you have on hand, here are some versatile substitutions that can help you achieve similar flavors and textures. These alternatives allow you to maintain the recipe’s integrity while catering to various needs.
- Ground Beef – Swap the ground beef for ground turkey or ground chicken.
- Spinach – If you do not have frozen spinach, you can use fresh spinach. Just make sure you sauté and chop it first. Kale can also be substituted, but it has a different flavor profile.
- Rolled Oats – If gluten isn’t a concern, you can easily substitute the oats with breadcrumbs. Alternatively, for a gluten-free option, almond flour works well, though it will give the meatballs a slightly different texture.
Step-by-Step Instructions

Step 1: Using a food processor, pulse mushrooms until finely chopped. Transfer to a bowl and then add the onion, and garlic to blender and pulse until finely chopped. Be careful not to over-pulse.

Step 2: In a large mixing bowl, combine all the ingredients. Shape into balls and transfer to lined or greased baking sheet. Bake for 15-20 minutes, or until meatballs are browned and cooked through.
Recipe Tips
- Cook quinoa in advance so it’s one less thing to do.
- Make sure to pulse the mushrooms in the food processor/blender separately, as it has a tendency to become too watery when combined with onion and garlic.
- Be careful not to overwork the meat! Otherwise, you’ll end up with tough meatballs. Hands are the best tool for mixing all the ingredients.
Variations

This recipe is great as it is, but here are some variations you can try to give it a unique twist. These variations allow you to explore different cuisines and flavor profiles while keeping the core recipe versatile and delicious.
- Mediterranean – Add chopped sun-dried tomatoes, crumbled feta, and dried oregano. Swap Italian seasoning for fresh parsley or basil to boost freshness.
- Asian-Inspired – Add soy sauce (or tamari to keep gluten-free), grated ginger, and chopped scallions. Replace quinoa with rice or cauliflower rice. Top with sesame seeds for added crunch.
- Vegan – Replace ground beef with a plant-based meat alternative, use nutritional yeast instead of parmesan. Use flax or chia seed eggs as an egg substitute.
Serving Suggestions
- Noodles – For a heartier meal, toss the meatballs in marinara sauce or another favorite tomato-free sauce. Serve them over pasta or zucchini noodles for a lighter twist.
- Wrap – You can also stuff them into a pita or quinoa tortilla with fresh veggies and a dollop of tzatziki or hummus for a quick and tasty wrap.
- Pairing the meatballs with a fresh salad, grain bowl, or roasted vegetables makes for a balanced and satisfying lunch or dinner.
Whether you’re craving something filling or light, these quinoa meatballs are a great choice!
Storage

Store in an airtight container for 3-4 days in the refrigerator.
Freeze for up to 3 months in freezer safe container or bag. I recommend using the flash freeze method to prevent them from sticking together.

Hi Min! Can I substitute cooked quinoa with ground quinoa?? Thanks!!
I’m not sure as I haven’t tried
Recently found you on IG and am loving your recipes. If I want to make batch of these to freeze, would you suggest freezing them after meatballs are formed but still raw or after cooking them? Thank you!
Thank you so much! I actually freeze them after cooking them. I’ve found that if I freeze the mixture, it gets too watery once thawed. Hope this helps!!

Sure you can use baby oat cereal
