When you’re looking to boost the nutritional value of your burger, spinach is really helpful – it’s packed with iron, vitamins, and minerals that transform a simple patty into a genuine health powerhouse. I’ve found that frozen spinach works beautifully because it’s already processed and easy to chop finely. You’ll want to mix it thoroughly with your other ingredients so the nutrients spread evenly throughout the patty. The spinach’s moisture content actually helps bind everything together, reducing the need for extra binders. Fry these patties thin and they’ll crisp up nicely while keeping that nutritional boost intact, giving you a burger that’s both delicious and genuinely good for you.

This recipe creates a satisfying plant-based burger that delivers both flavor and nutrition in every bite. The combination of frozen spinach, potatoes, and an array of vegetables creates a hearty base, while breadcrumbs, oats, and nutritional yeast provide structure and a savory depth that makes these patties both filling and delicious.
Popeye Burger Recipe (Spinach-Packed)
by veganpreps.com

Ingredients
- 10 oz (280g) frozen chopped spinach, thawed and squeezed very dry
- 1 large potato (about 250g), boiled and mashed
- 1 medium onion, finely diced
- 1 medium sweet red bell pepper, finely diced
- 1 cup French-style green beans, cooked and finely chopped
- 1 1/2 cups rolled oats
- 1/2 cup breadcrumbs
- 1/4 cup nutritional yeast flakes
- 1/4 cup unbleached all-purpose flour
- 1/2 cup barbecue sauce
- 1 tablespoon garlic powder
- 1 teaspoon seasoned salt
- 1/2 teaspoon sea salt
- 1/2 teaspoon paprika
- 1 teaspoon vegetable stock powder
- 1/3 teaspoon prepared mustard
- 1 tablespoon vegan margarine or neutral oil, for frying
Instructions
- 1Boil the potato until completely tender, about 15-20 minutes. Drain and mash until smooth. Thaw spinach, then wring out all excess moisture using a clean towel – it must be as dry as possible.
- 2In a large bowl, combine mashed potato, dried spinach, diced onion, bell pepper, chopped green beans, rolled oats, breadcrumbs, nutritional yeast, flour, barbecue sauce, garlic powder, seasoned salt, sea salt, paprika, stock powder, and mustard. Mix thoroughly until a firm, cohesive mixture forms. If too wet, add more breadcrumbs 1 tablespoon at a time.
- 3Divide mixture into 8 equal portions and shape into patties about 1/2 inch thick. Place on a plate and refrigerate for 15 minutes to firm up.
- 4Heat vegan margarine in a large non-stick skillet over medium heat. Cook patties in batches, without crowding, for 5-7 minutes per side until deep golden brown and heated through.
- 5Transfer cooked patties to a paper-towel-lined plate. Serve in burger buns with your preferred toppings.
Notes
- Store leftovers in an airtight container in the fridge for up to 4 days.
- This recipe freezes well for up to 3 months. Thaw overnight in the fridge before reheating.
- Adjust seasoning to taste after reheating, as flavors can mellow during storage.
I make sure the potato is fully cooked before chopping so it mixes in nicely with the other stuff. The frozen spinach needs to be thawed and I squeeze out all the extra moisture so the patties don’t get too wet. Since this recipe uses both garlic powder and chopped onion along with extra seasoning, I taste the mixture before forming patties to adjust the flavors how I like them. The thinner I form these patties, the crispier they get when fried, which creates a better texture and a nicer outside.
Microwave Potato Until Cooked

Begin by selecting 1 large potato and placing it on a microwave-safe plate. Pierce the potato several times with a fork to allow steam to escape during cooking. Microwave on high power for approximately 8-12 minutes, depending on the size of the potato and your microwave’s wattage. The potato is completely cooked when a fork easily pierces through to the center with no resistance. Once fully cooked, remove the potato from the microwave and allow it to cool slightly for easier handling.
After the potato has cooled enough to handle comfortably, finely chop it into small, uniform pieces. The size of the chopped pieces matters since they’ll be mixed with other ingredients to form the patty base. Set the chopped potato aside in a large mixing bowl where you’ll combine all the remaining ingredients. While preparing the potato, finely chop 1 medium onion and 1 medium sweet red bell pepper, then soften them in the microwave for 2-3 minutes to improve their tenderness and flavor before mixing.
Once all vegetables are prepared and cooled, combine them with the remaining ingredients including 10 ounces of frozen chopped spinach, 1 cup green beans, 1½ cups rolled oats, ½ cup bread crumbs, ½ cup barbecue sauce, and all the seasonings and other components listed in the recipe. Mix everything together thoroughly in your large mixing bowl until well combined, then proceed to form the mixture into thin patties for frying.
Try Bell Pepper Alternatives
If you don’t have sweet red bell peppers on hand or you’d prefer to experiment with different flavors, you’ve got plenty of options that’ll work just as well in your Popeye burger mixture. Yellow or orange bell peppers offer a slightly sweeter taste, while green peppers bring earthier notes. You could also try poblano peppers for more depth, or even roasted red peppers from a jar if you’re short on time. The key is softening whatever pepper you choose in the microwave, just like the recipe suggests. This makes sure you get even cooking and helps flavors blend throughout your patties.
Pair With Crispy Sweet Potato Fries
Once you’ve got your Popeye burgers sizzling in the pan, you’ll want to add a side that pairs well with all those earthy vegetables and hearty oats – and that’s where crispy sweet potato fries come in. I cut mine into thin wedges, toss them with a light coating of olive oil and sea salt, then bake them at 425 degrees until they’re golden and crispy on the outside but tender inside. The natural sweetness complements the savory burger, and you’ll like how the fries’ texture is different from your patty’s hearty density. Plus, you’re adding nutrition on top of nutrition.
Final Thoughts
Making your own veggie burgers from scratch is satisfying, and the Popeye burger shows you just how much flavor and nutrition you can pack into a single patty. Homemade versions beat store-bought every time because you control the ingredients and texture. The spinach adds iron and nutrients while the oats bind everything together perfectly. These patties hold up better when you make them thin, so they crisp up nicely. Using a veggie burger press* ensures your patties are evenly shaped and compact for optimal cooking results. Try this burger if you’re vegetarian or just exploring meatless options – it delivers real satisfaction without cutting corners.
