There’s something about springtime that just makes me want to host brunch! Maybe it’s the warmer weather, the fresh produce popping up, or just an excuse to gather friends around the table. For years, I stressed about finding the perfect brunch centerpiece – something elegant but easy, impressive but not fussy. Then, during one slightly chaotic Easter prep, I stumbled upon this combination, and oh my goodness, it was a game-changer! This Spring Vegetable & Swiss Egg Bake became my instant go-to.
It’s loaded with tender asparagus, earthy mushrooms, and that distinctively nutty Swiss cheese, all baked into a light, fluffy egg custard. It looks gorgeous on the table, tastes incredible, and happens to be low-carb and packed with veggies. Whether you need a star for your next brunch, a satisfying make-ahead breakfast, or even a light lunch or dinner, this bake is wonderfully versatile and always delicious.
Why This Recipe is a Keeper
- Flavor Harmony: The combination of slightly sweet asparagus, savory mushrooms, and nutty Swiss cheese is just chef’s kiss. The hints of Dijon and nutmeg add a subtle depth that makes it feel extra special.
- Healthy & Satisfying: It’s naturally low-carb and packed with protein and vegetables, keeping you full and happy without weighing you down. Perfect for a lighter-feeling yet substantial meal.
- Prep-Ahead Friendly: You can assemble parts of this ahead or bake the whole thing in advance, making it ideal for stress-free entertaining or easy weekday meals (more on meal prep below!).
Gather Your Ingredients
Here’s what you’ll need:
- 12 large Eggs: The foundation of our fluffy bake.
- 2.5 cups shredded Swiss Cheese: Nutty, melty goodness! Gruyere would also be a fantastic (though pricier) substitute.
- 10 Tbsp Milk: Whole or low-fat milk works perfectly fine here. Even unsweetened almond milk could work in a pinch for dairy-free needs (though it might slightly change the texture).
- 2.5 Tbsp Unsalted Butter: For sautéing the veggies and adding richness.
- 2.5 cups diced Asparagus: Look for stalks that are firm and bright green. Trim off the tough woody ends before dicing! (About 1 large bunch).
- 2.5 cups diced Mushrooms: Cremini (baby bellas) or white button mushrooms are great choices. (About 10-12 oz).
- 3 Tbsp minced Shallot: Adds a delicate onion flavor that’s milder than regular onion.
- 1 tsp Dijon Mustard: For a little tangy kick that complements the Swiss.
- Generous 1/2 tsp Kosher Salt or Sea Salt: Enhances all the flavors. Adjust to your taste.
- Generous 1/4 tsp Black Pepper, freshly ground: Freshly ground makes a difference!
- 1/4 tsp Ground Nutmeg: A classic pairing with eggs and cheese – adds a lovely warmth.
Equipment Needed:
- A trusty large skillet
- Large mixing bowl
- Whisk or fork
- Casserole dish (about 2.5-3 quarts – something like a 7×11 inch or a deep 9×9 inch dish works well)
Let’s Get Baking: Step-by-Step
- Prep Station: Get your oven preheating to 350°F (175°C) with the rack in the middle. Grease your casserole dish well – nobody likes stuck eggs!
- Sauté the Good Stuff: Melt the butter in your skillet over medium heat. Add those lovely minced shallots and stir them around for a minute until they smell amazing. Now, toss in the diced asparagus and mushrooms. Keep cooking and stirring often for about 6-8 minutes. You want the veggies to soften and the mushrooms to release their liquid – cooking off that liquid prevents a watery bake! Once they look right, take the skillet off the heat and spread the veggie mixture evenly in your greased dish.
- Cheese Blanket: Sprinkle all that yummy Swiss cheese evenly over the top of the vegetables.
- Egg Magic: Crack your eggs into the large mixing bowl. Pour in the milk, add the Dijon mustard, salt, pepper, and nutmeg. Whisk everything together really well until it’s smooth and evenly combined. You want those yolks and whites fully mixed!
- Combine & Ready for Oven: Gently pour the whisked egg mixture over the cheese and veggies in the dish. Try to pour it evenly so everything gets coated.
- Bake Time: Carefully place the dish in your hot oven. Let it bake for 40 to 45 minutes. It’s done when the center feels firm when you gently press it, and a knife stuck near the middle comes out clean. The top should be a beautiful light golden brown.
- Patience is Key! Okay, this is important: Once it’s out of the oven, let the bake rest on a wire rack for 10 minutes before you even think about slicing. This lets the eggs finish setting up, so your slices hold together beautifully.
Tips from My Kitchen
- Cheese Choices: While Swiss is classic, feel free to experiment! Gruyere, fontina, or even a sharp white cheddar would be delicious variations.
- Herb Heaven: Want more green? Add a tablespoon or two of fresh chopped chives or dill to the egg mixture along with the seasonings.
- Mushroom Prep: Don’t wash mushrooms under running water – they absorb it like sponges! Just wipe them clean with a damp paper towel before dicing.
- Avoid the Soggy Bottom: Really make sure you cook down the mushrooms until their liquid evaporates in step 2!
Your Meal Prep Lifesaver
This egg bake is fantastic for planning ahead!
- Make & Store: Bake the entire dish as directed. Let it cool completely on the counter. Once cool, cover it tightly (with plastic wrap or a lid) and pop it in the fridge. It will keep well for up to 4 days.
- Portion Power: For super easy grab-and-go meals, slice the cooled bake into individual portions and store them in airtight containers in the fridge.
- Gentle Reheating: To reheat, microwave individual slices on medium power (around 50-60%) for 60-90 seconds, or until just warmed through. You can also use a toaster oven on a low heat setting. Avoid blasting it on high heat, which can make the eggs rubbery.
Serving Suggestions
This bake is truly a star on its own, but here are some ideas:
- Brunch Hero: Serve alongside fresh fruit salad, yogurt, and maybe some crispy bacon or sausage.
- Light Lunch: Pair a slice with a simple green salad tossed with lemon vinaigrette.
- Easy Dinner: Enjoy with a side of roasted sweet potatoes (if not strictly low-carb) or steamed green beans.
- Simple & Elegant: A dollop of crème fraîche or a sprinkle of extra fresh herbs right before serving looks lovely.

Equipment
- Large skillet
- Large mixing bowl
- Whisk or fork
- Casserole dish (approx. 2.5-3 quart capacity, e.g., 7x11 inch, deep 9x9 inch, or similar)
Ingredients
- 12 large Eggs
- 2.5 cups shredded Swiss Cheese approx. 10 oz / 280g
- 10 Tbsp Milk whole or low-fat recommended
- 2.5 Tbsp Unsalted Butter approx. 35g
- 2.5 cups diced Asparagus from about 1 large bunch, trimmed
- 2.5 cups diced Mushrooms about 10-12 oz / 280-340g
- 3 Tbsp minced Shallot
- 1 tsp Dijon Mustard
- Generous 1/2 tsp Kosher Salt or Sea Salt
- Generous 1/4 tsp Black Pepper freshly ground
- 1/4 tsp Ground Nutmeg
Instructions
- Oven & Dish Prep: Position an oven rack in the center and preheat to 350°F (175°C). Thoroughly grease your casserole dish with butter or non-stick spray.
- Sauté Aromatics & Vegetables: Place the butter in the large skillet over medium heat. Once melted, add the minced shallots and cook, stirring, for about 1 minute until fragrant. Add the diced asparagus and mushrooms to the skillet. Continue to cook, stirring frequently, until the vegetables soften and the mushrooms release their liquid, about 6-8 minutes. Remove from heat and transfer the cooked vegetable mixture to the prepared casserole dish, spreading it evenly.
- Layer the Cheese: Sprinkle the shredded Swiss cheese uniformly over the layer of sautéed vegetables in the dish.
- Prepare Egg Custard: In the large mixing bowl, crack the eggs. Add the milk, Dijon mustard, salt, pepper, and ground nutmeg. Whisk vigorously until the eggs are well-beaten and all ingredients are thoroughly combined.
- Combine & Bake: Carefully pour the egg mixture over the cheese and vegetables in the casserole dish. Ensure the egg mixture distributes evenly. Place the dish into the preheated oven.
- Bake Until Set: Bake for 40 to 45 minutes. The bake is ready when the center is set (a knife inserted near the middle should come out clean) and the top is lightly golden brown.
- Rest Before Serving: Remove the bake from the oven and let it stand on a wire rack for 10 minutes before slicing and serving. This allows the eggs to fully set and makes slicing easier.
