Chicken Burgers with Feta Cheese & Spinach

If Chicken Burgers with Feta Cheese & Spinach sounds like something you’d order at a cute little café and then try to recreate at home… hi, welcome, you’re in the right kitchen. This is the kind of recipe that feels a little fancy, but is actually super doable on a regular Tuesday—aka the day you’re juggling life, laundry, and someone asking what’s for dinner while you’re still answering emails.

These burgers are juicy (thank you, spinach), tangy (hello feta), and basically built for people who want something fresh, satisfying, and not boring. Plus, we’re adding not one, but two dreamy sauces: a warm, creamy feta spread and a cool tzatziki situation that makes everything taste like you’re eating on a sunny patio… even if you’re in yoga pants in your kitchen.

Let’s make magic.

Why You’ll Love These Chicken Burgers with Feta Cheese & Spinach

• They’re flavorful without being fussy. The oregano, onion, garlic, and feta do the heavy lifting.
• They stay moist. Spinach is your secret weapon here (and no, it won’t taste like a salad).
• Meal-prep friendly. You can make both sauces ahead, and the patties hold up beautifully.
• They impress people. If you serve these at a cookout, someone will absolutely ask, “Wait… YOU made these?”

And if you’ve got picky eaters? Call them “Greek chicken sliders” and watch the curiosity kick in. (Marketing works on adults too.)

Ingredients You’ll Need

You’ve got three parts: Feta Cheese Spread, Tzatziki Sauce, and Burger Patties + Toppings.

Feta Cheese Spread

• 2 ounces feta cheese
• 4 ounces cream cheese
• 1 large garlic clove, minced

Tzatziki Sauce

• 2 large garlic cloves, minced
• ¼ cup English cucumber, finely chopped (about 3 ½ ounces)
• 2 tablespoons dill, finely chopped
• 1 tablespoon fresh lemon juice (½ lemon, juiced)
• 1 tablespoon extra virgin olive oil
• ¼ teaspoon salt
• Dash of freshly ground pepper

Burgers

• 10 ounces frozen chopped spinach, thawed and thoroughly squeezed dry
• 1 pound ground chicken (93% lean)
• 4 ounces feta cheese, finely crumbled
• ¼ cup almond meal or breadcrumbs
• 1 medium yellow onion, finely chopped
• 6 cloves garlic, minced
• 1 teaspoon salt
• 1 teaspoon pepper

How to Make Chicken Burgers with Feta Cheese & Spinach

1) Make the Feta Cheese Spread

Add all feta spread ingredients to a small microwave-safe bowl.

• Microwave 30 seconds, then stir.
• If it’s still lumpy, microwave 15–30 seconds more and stir again.

Alternative: Toss everything into a food processor and pulse until smooth and creamy.

Make-ahead tip: You can make this the day before and keep it covered in the fridge.

2) Mix the Tzatziki Sauce

In a bowl, stir together all tzatziki ingredients.

Pop it in the fridge while you make the burgers. This helps the flavors blend and mellow (especially the garlic—because garlic that’s too loud is… a lot).

Also make-ahead friendly: Make it the day before if you want.

3) Prep the Spinach (This Part Matters!)

Thaw the spinach in the microwave, let it cool, then squeeze out ALL the liquid.

Like… really squeeze it. Pretend the spinach owes you money.

Why? Because extra water = mushy patties. Dry spinach = juicy burgers that hold together.

4) Mix and Shape the Patties

In a large bowl, add:

• Ground chicken
• Squeezed spinach
• Crumbled feta
• Almond meal/breadcrumbs
• Onion
• Garlic
• Salt, pepper, oregano

Mix thoroughly (clean hands are easiest). Then shape into 4 equal patties.

Tip: Make a small indent in the center of each patty. It helps them cook evenly and keeps them from puffing up like a meatball in disguise.

5) Grill to Perfection

Preheat grill to 450°F.

• Spray patties on both sides with grilling spray.
• Grill 5 minutes on the first side.
• Flip and grill 3–5 minutes more, until the internal temp hits 165°F in the center.

If you’re using Mesquite smoke chips, place them in a smoker box over heat for about 7 minutes until smoking, then grill the burgers.

6) Assemble Like a Pro

Smear the Feta Cheese Spread inside the buns.

Add:

• Burger patty
• Lettuce
• Tomato
• Cucumber slices
• Red onion
• Spoon tzatziki on top

Take a bite and try not to do that little “mmm” noise. (No promises.)

Quick Tips From My Kitchen

• Dry spinach is everything. If your patties feel too wet, add a little more almond meal or breadcrumbs.
• Don’t overmix. Mix just until everything is combined. Overmixing = tougher burgers.
• Use a meat thermometer. Chicken needs to hit 165°F—no guessing games.
• Toast your buns. A quick toast adds crunch and helps hold the sauces (aka prevents the “soggy bun sadness”).
• Sauce strategy: Put feta spread on the bun, tzatziki on the burger. It keeps the flavors layered and less messy.

And if your feta spread looks a little weird at first? Stir it like you mean it. It’s not a failure—it’s just “rustic.”

A Little Story From My Chicken Magic Life

The first time I made Chicken Burgers with Feta Cheese & Spinach, I was trying to convince my family that ground chicken could be exciting. (Ground chicken has a reputation for being… polite. Like it apologizes for existing.)

So I added feta, spinach, garlic, and those two sauces—and suddenly everyone was hovering near the grill asking, “When are they done?” That’s when I knew this recipe was a keeper. Now it’s my go-to when I want something that feels fun but still fits into real-life cooking.

Serving Ideas and Easy Swaps

• Low carb / keto-ish option: Skip the brioche bun and serve as a lettuce wrap burger or over a big salad.
• Pita-style: Stuff the patty into a warm pita with toppings and sauces.
• Meal-prep bowls: Chop the burger and serve over rice, quinoa, or cucumber-tomato salad with tzatziki.
• No grill? Use a grill pan or skillet (medium-high heat) and cook until 165°F inside.

FAQs About Chicken Burgers with Feta Cheese & Spinach

Can I use fresh spinach instead of frozen?

Yes! Cook it down first, cool it, then squeeze it dry. You want the same “dry as possible” result so your Chicken Burgers with Feta Cheese & Spinach don’t fall apart.

What can I substitute for almond meal?

Breadcrumbs work perfectly (you already have that option). If you’re gluten-free, use gluten-free breadcrumbs or even crushed gluten-free crackers.

How do I store leftovers?

Store cooked patties in an airtight container in the fridge for 3–4 days. Keep the feta spread and tzatziki separate. Reheat patties gently (microwave or skillet) so they stay juicy.

Can I freeze the patties?

Yes. Freeze uncooked patties on a parchment-lined tray, then transfer to a freezer bag. They’ll keep well for about 2–3 months. Thaw in the fridge before grilling.

What if my mixture feels too wet?

That usually means the spinach wasn’t squeezed enough. Add 1–2 tablespoons more almond meal or breadcrumbs, and you’ll be back in business.

Your New Favorite Burger Night
