The eggs are the heart of these muffins, so use large, fresh eggs—room temperature makes a difference for fluffiness. Trader Joe's or Costco often have the best prices for organic eggs in bulk, and I always grab extra for baking. Cream cheese adds that luxurious texture, so don’t skimp—Philadelphia brand is my go-to, but any full-fat cream cheese works. For the mushrooms, shiitakes hold up best to sautéing—their meaty texture contrasts perfectly with the eggs. If you can’t find shiitakes, cremini mushrooms are a solid swap, but they’ll be slightly less earthy. The spinach? Baby spinach leaves are easiest to chop, but any fresh spinach works—just make sure it’s dry before mixing.
No cream cheese? Greek yogurt at half the amount keeps things creamy, though the texture will be slightly lighter. Fresh herbs are ideal, but dried dill or chives at one-third the amount will work in a pinch—just rehydrate them in warm water for 5 minutes first. Want extra cheesiness? Add feta or goat cheese alongside the cheddar, but reduce the total cheese by 2 tablespoons to keep the muffins from getting too dense. The flour is optional but helps create crispier edges—skip it if you prefer a softer texture. For the sautéed mushrooms, don’t overcook them—they should be tender but still hold their shape, or they’ll turn to mush in the muffins.
These muffins reheat like a dream—30 seconds in the microwave or 10 minutes in a 350°F oven brings back that golden, crispy edge. Store them in an airtight container in the fridge for up to 5 days, or freeze for up to 3 months by lining a tray with parchment and freezing before transferring to a bag. I always make a double batch—half for the week, half for flash-frozen portions. The flavor actually deepens overnight, so leftovers are often the best part.

Step-by-step instructions for spinach mushroom egg muffins
Here's how to assemble these savory bites with perfectly set yolks and crispy edges.
Sauté Mushrooms and Aromatics for Maximum Flavor
Heat a nonstick skillet over medium heat and melt 1 tablespoon of the unsalted butter. Add the 0.5 lb shiitake mushrooms, sliced thin, and cook for 5-6 minutes until they release their moisture and develop golden edges. This is where the umami magic happens—don't rush this step.
Push the mushrooms to one side of the pan and add the remaining 1 tablespoon butter. Toss in the 3 minced garlic cloves and cook for 30 seconds until fragrant but not browned. Immediately stir the garlic into the mushrooms to prevent burning. Let this mixture cool completely before using—hot mushrooms will scramble your eggs.
Whisk Egg Mixture to Perfect Texture
In a large bowl, whisk together the 8 room temperature eggs and 0.5 cup whole milk until just combined—no need to make it frothy. Add the 0.25 cup all-purpose flour and whisk until evenly distributed. This creates a light batter that will yield fluffy muffins with crispy edges.
Fold in the 4 oz softened cream cheese using a silicone spatula until completely melted and smooth. Then stir in the sautéed mushroom and garlic mixture, 2 cups chopped spinach leaves, 0.5 cup shredded cheddar cheese, 0.25 cup chopped chives, and 0.25 cup chopped dill. Season with 0.5 teaspoon kosher salt and 0.25 teaspoon black pepper. The batter should be thick but pourable—if it's too stiff, add 1-2 tablespoons milk to thin it.
Prepare Muffin Tin for Perfect Release
Preheat your oven to 350°F. Generously butter a 12-cup muffin tin with the remaining butter, making sure each cup is well coated. I like to use a pastry brush for even distribution. The butter creates a barrier that prevents sticking and ensures those crispy edges we're after.
Divide the egg mixture evenly among the muffin cups, filling each about ¾ full. For perfectly round muffins, use a spoon to gently smooth the tops. The batter will puff as it bakes, so don't overfill. Place the muffin tin on a baking sheet to catch any potential overflow.
Bake to Golden Perfection with Herbed Yolk Magic
Bake for 18-20 minutes until the edges are golden brown and the centers are just set. You'll know they're ready when a toothpick inserted comes out clean—no uncooked egg should cling to it. The tops should be slightly puffed with a crispy texture that gives way to a tender interior.
For that signature herbed yolk center, I recommend underbaking by 1 minute if your oven runs hot. The residual heat will finish cooking the muffins while keeping the yolks beautifully runny. Let them cool in the pan for 5 minutes before transferring to a wire rack—this helps them set completely and makes them easier to remove.
Serve Warm with Fresh Herbs for Extra Flavor
Garnish each muffin with an extra sprinkle of chives and dill right before serving. The fresh herbs add a bright contrast to the rich egg mixture and make these look like they came from a gourmet café. Serve immediately while the yolks are still warm and creamy—this is when they're at their most luxurious.
These muffins keep well in the refrigerator for 3 days, but I find they're best enjoyed fresh. For a quick breakfast or snack, you can reheat them in the oven at 300°F for 5-7 minutes to restore that crispy texture. The flavor combination of earthy mushrooms, fresh herbs, and creamy eggs makes these a standout savory option any time of day.
Pro Tips For Making Spinach Mushroom Egg Muffin
- Sauté Mushrooms First: I learned this the hard way—raw shiitake mushrooms turn egg muffins into a soggy mess. Sear them in a dry pan for 3-4 minutes until they release their moisture and develop a crisp edge. Then chop them fine so they distribute evenly in the batter.
- Wilt Spinach Properly: Fresh spinach packed with water = sad, watery muffins. Give those leaves a quick sauté in a hot, oiled pan for just 30 seconds—until they’re limp but still vibrant green. Drain well before mixing into the egg, or your muffins will steam instead of bake.
- Mix Cream Cheese Cold: Room-temperature cream cheese makes the batter too soft, leading to collapsed muffins. Cut that block straight from the fridge and grate it directly into the egg mixture. The cold fat will create pockets of richness without weighing down the texture.
- Preheat Pan Fully: I used to rush this, and my muffins would steam instead of set. A nonstick skillet or muffin tin needs to be screaming hot (425°F) for 5 minutes before adding batter. This guarantees a golden crust on the bottom and keeps the centers tender—not rubbery.
Make-ahead tips for spinach mushroom egg muffin
Batch Prep Strategy
Double the recipe and divide into two 12-cup muffin tins—this ensures you have enough for the week without leftovers. I always bake both batches simultaneously on different oven racks for even cooking. The extra muffins freeze beautifully, so I store half in the freezer and half in the fridge.
This way, I can grab one straight from the freezer for a quick breakfast without thawing. 💫
Freezer Storage Hacks
Line a baking sheet with parchment paper before freezing individual muffins. This prevents them from sticking together and makes reheating easier. Once completely frozen (2-3 hours in the freezer), transfer to a ziplock freezer bag with all air squeezed out.
Label with the date—these keep for 3 months without losing texture. I like to portion them into 4-muffin packs for easy grab-and-go servings.
Thawing and Reheating
For a quick breakfast, microwave frozen muffins for 45-60 seconds on 50% power—this gently warms them without drying out the yolks. For best texture, reheat in a 350°F oven for 8-10 minutes until golden and crispy.
I always add a splash of water to the muffin tin before reheating to restore moisture. The flavor actually improves after freezing, as the spices meld together over time. 🔥
Portion Control Tips
Use quart-sized meal prep containers to store 3-4 muffins each—perfect for lunchboxes or work snacks. I pack them with a small container of hot sauce or sriracha for dipping, which adds a fun interactive element.
For portion control, I weigh the muffins before freezing: each one should be about 50-60 grams (about 2 oz), making them easy to track for meal planning.
Weekly Prep Schedule
I dedicate one Sunday morning to making a full batch of these muffins. While they bake, I prep other components like roasted sweet potatoes or a simple salad for balanced meals.
The muffins stay fresh in the fridge for 4 days, and I rotate them with frozen portions throughout the week. This system saves me 15-20 minutes daily on breakfast prep—game-changer for busy mornings! ✨

Frequently asked questions
Can I make these egg muffins without cream cheese?
Replace the 4 oz cream cheese with ½ cup Greek yogurt or ¼ cup sour cream for a lighter texture. The yogurt adds creaminess while keeping the muffins fluffier. For extra richness, use 2 oz goat cheese instead—it melts beautifully and adds a tangy depth.
How do I keep the yolks from cooking all the way through?
Bake for 18 minutes instead of 20, then let them sit in the oven for 2 minutes off heat. The residual warmth keeps yolks runny while the edges set. For extra insurance, use a 325°F oven—the lower temp prevents overcooking. Serve immediately for that perfect herbed yolk center!
Can I use frozen spinach instead of fresh?
Yes, but thaw and drain it first to remove excess water. Use 1 cup thawed spinach (about 2 oz) instead of 2 cups fresh. Overcooked spinach releases too much moisture, making the muffins soggy. Squeeze out any liquid with a paper towel before mixing for best results.
Why did my muffins turn out dense instead of fluffy?
Overmixing the batter or using cold eggs are the most common culprits. Whisk eggs and milk just until combined, then gently fold in other ingredients. Room-temperature eggs (70°F) incorporate air better. Also, ensure your oven isn't too hot—350°F is critical for even baking. A toothpick inserted should come out clean, not wet.
What's the best way to reheat these for breakfast?
For crispy edges, reheat in a 350°F oven for 8-10 minutes on a baking sheet. For speed, microwave for 20-30 seconds on 50% power—add a damp paper towel to prevent drying. The oven method restores that golden crust, while the microwave keeps yolks perfectly runny.
