Savory Crepe with Spinach Mushroom

The tiny apartment kitchen in Paris had a window that opened to a courtyard where someone always played accordion on Sunday mornings. My landlady taught me to make crepes by gesture mostly, since my French was terrible and her English nonexistent.

Last summer I made these for my sister who swore she hated spinach. She ate three filled crepes standing at the counter, and now she requests them every time she visits. The mushrooms get caramelized and sweet while the cheese melts into everything.

Ingredients

• 1 cup all purpose flour: This foundation creates the tender structure, and sifted flour prevents any lumps in your batter
• 2 large eggs: Room temperature eggs incorporate better and help the crepes develop that signature delicate golden color
• 1¼ cups milk: Whole milk creates the richest texture, though any milk works in a pinch
• 2 tablespoons melted butter: Adding butter directly to the batter keeps the crepes tender and prevents sticking
• ¼ teaspoon salt: This small amount enhances all the other flavors without making the crepes taste salty
• 2 tablespoons olive oil: The oil helps the vegetables caramelize beautifully without burning
• 1 small onion: Finely chopped onion dissolves into the filling, providing a sweet aromatic base
• 2 cups fresh spinach: Fresh spinach wilts down to concentrate its earthy flavor and complements the rich cheese
• 1 cup mushrooms: Button or cremini mushrooms develop deep umami notes when cooked properly
• ½ cup grated Gruyère: This cheese melts exceptionally well and adds a nutty complexity that elevates the whole dish

Instructions

Prepare the batter:

Whisk flour and salt in a bowl, create a well in the center, and crack eggs into it. Gradually whisk in half the milk until smooth before adding the remaining milk and melted butter. Let the batter rest for 10 minutes so the flour fully hydrates.

Cook the crepes:

Heat a nonstick skillet over medium heat and brush with melted butter. Pour about ¼ cup batter into the pan, immediately tilting and swirling to coat the bottom in a thin even layer. Cook 1 to 2 minutes until edges curl up and the bottom is golden, then flip and cook 1 minute more.

Make the filling:

Warm olive oil in a skillet and sauté chopped onion until soft and translucent. Add sliced mushrooms and cook until they release their liquid and turn golden brown. Toss in spinach and stir just until wilted, then season generously with salt and pepper.

Assemble and finish:

Spoon 2 tablespoons of filling onto each crepe and sprinkle with Gruyère. Fold the crepe in half or roll it up, then return to the warm skillet for 1 to 2 minutes per side until the cheese melts completely.

My daughter now stands on a stool to help swirl the pan, her small hands mimicking the motion she has watched me do hundreds of times. Some traditions get passed down without words.

Choosing the Right Pan

A dedicated crepe pan has very low sides which make flipping easier, but any nonstick skillet works perfectly well. The key is finding a pan that heats evenly and allows the batter to spread thinly across the entire surface.

Making Ahead

Crepes can be stacked between wax paper and refrigerated for up to 2 days or frozen for a month. The filling can also be prepared in advance and reheated gently before assembling.

Serving Suggestions

A simple green salad with vinaigrette cuts through the richness, and a crisp white wine complements the cheese beautifully. For brunch, add fresh fruit and maybe some bacon on the side.

• Try ham and gruyère for a classic combination
• Sautéed leeks and goat cheese feel particularly elegant
• Leftover ratatouille makes an incredible filling

These crepes have become our go-to when we want something special but not complicated. The filling possibilities are endless, which keeps everyone coming back for more.

Questions & Answers About the Recipe

→ What makes crepes tender and thin?

The key is a slightly runny batter and proper resting time. Letting the mixture sit for 10 minutes allows flour to absorb liquid fully, preventing toughness. Using melted butter adds richness and helps achieve that signature delicate texture.

→ Can I make the batter ahead of time?

Absolutely. The batter actually improves after resting in the refrigerator for up to 24 hours. This allows the flour to fully hydrate and results in even more tender crepes. Just whisk briefly before cooking to reincorporate any separation.

→ What other fillings work well?

The possibilities are endless. Try ham and Gruyère, smoked salmon with cream cheese, ratatouille, ricotta with herbs, or even caramelized onions and goat cheese. Sweet options include Nutella with bananas or lemon sugar.

→ How do I prevent crepes from tearing?

Ensure your skillet is properly heated but not smoking. Use just enough butter to coat the surface—too much causes splattering and uneven cooking. Wait until edges lift naturally before flipping. A non-stick pan or well-seasoned crepe pan makes the process easier.

→ Can these be made gluten-free?

Yes, simply substitute buckwheat flour for all-purpose flour. Buckwheat crepes, known as galettes in Brittany, have a nutty flavor and work beautifully with savory fillings. The technique remains the same.

→ What's the best way to reheat leftover crepes?

Place them in a skillet over low heat for about 30 seconds per side, or microwave between damp paper towels for 15-20 seconds. For best results, fill fresh crepes rather than refrigerating assembled ones, as the filling can make them soggy.
