• Low-carb bread: Look for a sturdy keto bread that holds up well to flipping. It provides the essential, crunchy structure for our sandwich.
• Feta cheese: Creamy and sharp, this ingredient adds a delightful Mediterranean tang. It crumbles beautifully and softens into a rich filling.
• Shredded mozzarella: This cheese provides the ultimate gooey melt and iconic cheese pull. It balances the sharp notes of the feta perfectly.
• Fresh spinach: Earthy and nutrient-dense, it wilts gently inside the warm sandwich. Make sure to sauté it briefly to remove excess moisture.
• Sun-dried tomatoes: These packed gems offer a concentrated burst of sweet, smoky flavor. Chop them finely so they distribute evenly in every bite.
• Garlic powder: A subtle dash introduces a wonderful savory depth. It elevates the spinach and cheese combination effortlessly.
• Red pepper flakes: This optional spice adds a gentle, warming kick. It cuts through the richness of the melted cheeses beautifully.
• Mayonnaise: Spreading this on the exterior ensures a perfectly even, golden-brown crust. It burns less easily than traditional butter.

How to make this Feta Grilled Cheese Sandwich with Spinach

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Step 1- Heat a small skillet over medium heat and lightly sauté the fresh spinach until it fully wilts.

Step 2- Remove the spinach from the heat and squeeze out any excess moisture using a paper towel.

Step 3- Spread a thin, even layer of mayonnaise on one side of each slice of low-carb bread.

Step 4- Place one slice of bread, mayonnaise-side down, into a cold skillet.

Step 5- Layer half of the mozzarella, followed by the cooked spinach, crumbled feta, and chopped sun-dried tomatoes.

Step 6- Sprinkle the garlic powder and red pepper flakes evenly over the top of the filling layers.

Step 7- Top with the remaining mozzarella cheese and place the second slice of bread on top, mayonnaise-side up.

Step 8- Turn the heat to medium-low and cook the sandwich slowly until the bottom is perfectly golden brown.

Step 9- Carefully flip the sandwich over and press down gently with a spatula.

Step 10- Cook for an additional three to four minutes until the cheese is completely melted and gooey.

Step 11- Slice the sandwich diagonally and serve it immediately while it is hot and crispy.

Common Mistakes to Avoid

• Using wet spinach: If you do not squeeze the water out of the spinach, your sandwich will become incredibly soggy.
• Cooking on high heat: High heat will quickly burn the bread before the cheese inside has a chance to melt properly.
• Overloading the filling: Piling too many ingredients inside makes the sandwich difficult to flip and causes the filling to spill out.

Required Equipment

• Non-stick skillet: Prevents the cheese from sticking to the surface and ensures an incredibly even, beautiful browning.
• Wide spatula: Allows you to flip the loaded sandwich carefully without losing any of the delicious filling.
• Paper towels: Essential for squeezing out the excess moisture from the sautéed spinach before assembling.

Caleb’s Recipe Tips

• Mix your cheeses first: Try tossing your crumbled feta and shredded mozzarella together in a small bowl before assembling. Trust me, I’ve learned this the hard way, as it ensures a much more even melt throughout the sandwich!
• Keep the heat low: Give your sandwich time to develop a crust by keeping the burner on medium-low. This patience allows the heat to penetrate deep into the center, melting the feta beautifully.
• Add a splash of acid: If you want to brighten up the heavy flavors, try adding a tiny squeeze of fresh lemon juice to the spinach. It cuts through the rich cheese and makes the whole dish pop.
• Use oil from the tomato jar: Instead of using regular oil to sauté your spinach, use a teaspoon of the oil from your sun-dried tomato jar. This quick hack infuses the greens with incredible, deep savory flavor from the start.

Storage Instructions

While this sandwich is absolutely best enjoyed fresh from the skillet, you can store leftovers if necessary. First, allow the sandwich to cool completely to prevent condensation from forming. Next, place it into an airtight container and store it in the refrigerator for up to two days. I do not recommend freezing this recipe, as the spinach and feta texture will change significantly upon thawing. When you are ready to reheat, place it back onto a dry skillet over low heat until the cheese melts and the bread crisps up again.
