Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Grease a 9-inch pie dish with butter or nonstick cooking spray.
Step 2: Cook the Spinach
Melt the butter in a skillet over medium heat.
Add the garlic and cook for 30 seconds until fragrant.
Add the spinach and cook until just wilted, about 2 minutes.
Remove from the heat and let cool slightly.
Step 3: Prepare the Egg Mixture
In a large bowl, whisk together:
Eggs
Heavy cream
Onion powder
Paprika
Salt
Black pepper
Stir in the Swiss cheese, mozzarella, and Parmesan.
Step 4: Assemble the Quiche
Spread the cooked spinach evenly in the prepared pie dish.
Scatter the lump crab meat over the spinach.
Pour the egg and cheese mixture over the top.
Gently stir with a fork to distribute the ingredients evenly.
Step 5: Bake
Bake for 35–40 minutes, or until the center is set and the top is lightly golden.
A knife inserted into the center should come out clean.
Step 6: Rest and Serve
Allow the quiche to rest for 10 minutes before slicing.
Garnish with parsley or chives and serve with lemon wedges if desired.
Expert Tips
Use Quality Crab Meat
Fresh or refrigerated lump crab meat provides the best flavor and texture.
Avoid Overbaking
Remove the quiche once the center is just set to keep it creamy.
Drain Excess Moisture
If using frozen spinach, thaw and squeeze out as much liquid as possible before adding it.
Let It Rest
Resting helps the quiche firm up for cleaner slices.
Delicious Variations
Seafood Florentine
Add cooked shrimp or chopped scallops along with the crab.
Spicy Version
Mix in a pinch of cayenne pepper or red pepper flakes.
Extra Cheesy
Use Gruyère or sharp cheddar in place of Swiss cheese.
Herb-Loaded
Add fresh dill, parsley, or thyme for even more flavor.
