Full Recipe:

• 1 tablespoon extra virgin olive oil

• 1 (7-oz or 200g) bunch lacinato kale (dinosaur kale), ribs removed, leaves thinly sliced

• Salt and freshly ground black pepper, to taste

• 5 oz (140g) cremini mushrooms, finely chopped

• 1 small yellow onion, thinly sliced (about 1 cup)

• 1/2 loaf (185g) ciabatta bread, cut into 1/8-inch-thick slices

• 3 large eggs

• 1 1/2 cups (375ml) milk

• 4 oz (112g) sharp cheddar cheese, grated

Directions:

1. Preheat oven to 350°F (180°C). Grease an 8-inch square baking dish with olive oil.

2. In a large skillet over medium heat, sauté the kale in olive oil until just wilted, about 2–3 minutes.

3. Add mushrooms and onions. Season with salt and pepper. Cook over medium-high heat, stirring frequently until mushrooms release their moisture and onions become translucent (3–5 minutes). Let cool for 5 minutes.

4. In a medium bowl, whisk together the eggs and milk.

5. Layer the casserole: Start with one-third of the ciabatta slices, then half of the sautéed mixture, then one-third of the cheese. Repeat once more. Finish with the last third of the bread.

6. Pour the egg-milk mixture over the entire casserole, pressing down with a spatula to help the bread absorb the liquid. Top with the remaining cheese.

7. Let sit for 15 minutes to soak while the oven finishes preheating. Cover with foil.

8. Bake covered for 30 minutes, then uncover and bake for an additional 25–30 minutes until golden and bubbly.

9. Allow to rest for a few minutes before slicing and serving.

A Hearty Vegetarian Classic: Kale, Mushroom, and Cheddar Bake

The Kale, Mushroom, and Cheddar Bake is a beautiful convergence of comfort food and wholesome ingredients. This rustic casserole has become a staple in many home kitchens due to its rich flavors, ease of preparation, and flexibility in adapting to different diets and occasions. With a foundation of crusty ciabatta bread soaked in a savory egg and milk custard, layered with sautéed kale, mushrooms, onions, and sharp cheddar, the dish is both deeply satisfying and nourishing.

Ideal for breakfast, brunch, or a casual weeknight dinner, this vegetarian bake carries a rustic charm that feels homemade and heartwarming. Let’s dive into what makes this dish such a crowd-pleaser and a favorite for meal preppers, busy parents, and anyone looking to elevate their vegetable-based cooking.

A Brief History of Strata-Inspired Dishes

The concept behind the Kale, Mushroom, and Cheddar Bake is deeply rooted in traditional strata dishes. Strata—derived from the Latin word for “layers”—is an American casserole typically made with bread, eggs, and cheese, often combined with vegetables or meat. Popularized in the mid-20th century, strata recipes were often featured in home economics cookbooks and became a go-to for holiday brunches.

Over time, the strata evolved from its meat-heavy roots to embrace more plant-forward variations. This adaptation uses kale and mushrooms to achieve that rich, umami base without any meat. The beauty of a strata-style bake lies in its layering, allowing flavors to meld during baking and textures to shift from soft and custardy to crisp and golden on top.

Why Kale, Mushrooms, and Cheddar?

Each primary component in this recipe brings something unique to the table—flavor, texture, and nutrition:

• Kale: A powerhouse leafy green, kale is packed with vitamins A, K, and C, and is known for its hearty structure, which holds up well during cooking. Lacinato kale (also known as Tuscan or dinosaur kale) is particularly well-suited for baking because it softens just enough while retaining some bite.

• Mushrooms: Cremini mushrooms (baby bellas) are used in this version, bringing a robust umami flavor and meaty texture that makes the dish feel indulgent and filling. They also provide minerals like selenium and B vitamins, adding a nutritional boost.

• Cheddar Cheese: Sharp cheddar adds richness and tang, offering a perfect counterpoint to the earthiness of the kale and mushrooms. Its excellent melting quality binds the layers and adds a gooey, comforting finish to every bite.

These ingredients, when combined, create a balance of flavors that’s both savory and satisfying without feeling heavy.

The Role of Bread in the Bake

What truly ties the dish together is the ciabatta bread. Cut into thin slices, it acts as both a sponge and a structural element. The bread soaks up the egg and milk mixture, softening in the center while maintaining a crisp edge on top.

Choosing the right kind of bread makes a noticeable difference. Ciabatta, with its open crumb and chewy crust, absorbs liquid beautifully without becoming mushy. Day-old or slightly stale bread works best, as it holds its shape and creates a more defined texture in the finished casserole.

Meal Prep and Make-Ahead Friendly

One of the most appealing aspects of the Kale, Mushroom, and Cheddar Bake is how easily it fits into busy lifestyles. The casserole can be assembled ahead of time, stored in the fridge overnight, and baked fresh the next day. In fact, letting it rest overnight enhances the flavor and allows the bread to fully soak in the custard, resulting in a more cohesive and flavorful bake.

This make-ahead quality makes it perfect for holiday gatherings, weekend brunches, or weekday meal prepping. A single 8-inch square pan yields generous servings and can be paired with a fresh salad or seasonal fruit for a complete meal.

Versatility and Ingredient Swaps

Flexibility is another strength of this recipe. While the original uses kale and cremini mushrooms, there’s room for experimentation:

• Greens: Swap kale for chard, spinach, or collard greens. Just be mindful of their water content and cook them down to prevent sogginess.

• Cheese: Replace cheddar with Gruyère, fontina, or mozzarella for a different flavor profile. A bit of parmesan sprinkled on top adds a savory, umami finish.

• Bread: Any rustic bread like sourdough or French baguette can work. Avoid overly soft sandwich bread as it may dissolve into the custard.

• Add-ins: Roasted red peppers, sun-dried tomatoes, or sautéed leeks can be layered in for extra color and flavor.

These variations ensure the bake can reflect seasonal produce, dietary preferences, or just what’s available in the pantry.

Nutrition and Health Considerations

Despite its comforting richness, this bake offers substantial nutritional value. Each serving is well-balanced, offering protein from the eggs and cheese, fiber and antioxidants from the kale, and energy-sustaining carbs from the bread. At around 276 calories per serving, it’s a wholesome option that doesn’t feel overly indulgent.

For those with dietary restrictions, simple adjustments can be made:

• Dairy-Free: Use a plant-based milk (like oat or almond) and dairy-free cheese.

• Gluten-Free: Use gluten-free bread that holds its shape when soaked.

• Low-Sodium: Reduce the cheese amount or use a low-sodium alternative, and season the veggies lightly.

With a few thoughtful tweaks, this dish can cater to various needs without sacrificing flavor or texture.

Serving Suggestions

This bake is incredibly versatile in how it can be served:

• Brunch: Pair with a fruit salad, yogurt parfait, or mimosa for a celebratory weekend spread.

• Lunch: Serve alongside a bowl of tomato soup or a crisp arugula salad with lemon vinaigrette.

• Dinner: Add roasted vegetables or a side of beans for extra protein.

It also reheats beautifully in the oven or microwave, making leftovers just as enjoyable as the original serving.

Seasonal Appeal and Presentation

The warm, rustic presentation of the Kale, Mushroom, and Cheddar Bake makes it particularly appealing in the fall and winter months, but it’s delicious all year round. The golden, cheesy crust with the vibrant green of the kale and earth-toned mushrooms gives it an inviting look that feels homemade and gourmet at the same time.

For special occasions, you can serve it in individual ramekins or mini cast-iron skillets for a personalized touch. A light sprinkle of fresh herbs like parsley or thyme adds color and brightness right before serving.

A Comforting Conclusion

In a world of fast meals and takeout, there’s something deeply rewarding about preparing a casserole from scratch that brings comfort and nourishment to the table. The Kale, Mushroom, and Cheddar Bake is more than just a recipe—it’s an invitation to slow down, use simple ingredients thoughtfully, and enjoy food that’s both soul-satisfying and nutritious.

Whether you’re making it for a cozy brunch with friends, prepping weekday meals for your family, or simply indulging in a self-care Sunday bake, this dish deserves a permanent spot in your cooking repertoire. Its flexibility, ease of preparation, and rich flavor profile make it a classic worth revisiting time and time again.
