A Savory Twist on a Classic Comfort Food: Caramelized Onion Spinach Feta French Toast Casserole

As a busy professional, finding time to cook a satisfying and delicious meal can sometimes feel like a mission impossible. Weekends are precious, and I don't want to spend my free time slaving away in the kitchen. That's why I'm always on the lookout for recipes that are both impressive and surprisingly easy to prepare. This Caramelized Onion Spinach Feta Savory French Toast Casserole is one such recipe. It's a stunning dish that delivers a delightful mix of sweet and savory flavors, and the best part? It's mostly hands-off once you get it in the oven.

The beauty of this casserole lies in its versatility. You can easily adapt it to your preferences and what you have on hand. Feel free to experiment with different cheeses, add mushrooms or other vegetables, or even change up the herbs. The caramelized onions add a depth of sweetness that perfectly complements the salty feta and the earthy spinach. The French bread, preferably day-old for optimal results, soaks up the custard beautifully, resulting in a texture that's both tender and satisfying. It's a dish that's hearty enough for a weekend brunch, impressive enough for a dinner party, and yet simple enough for a weeknight meal when you're short on time.

The process of making this casserole is surprisingly straightforward. The most time-consuming part is caramelizing the onions, but even that's manageable. While the onions are slowly developing their rich, sweet flavor, you can prepare the rest of the ingredients. It's a perfect example of a recipe where a little bit of upfront effort results in a magnificent reward. The aroma that wafts from the oven as it bakes is simply irresistible, a promise of the deliciousness to come.

This casserole is also incredibly forgiving. If you don't have fresh thyme, you can easily substitute dried. If you prefer a different type of milk, feel free to experiment. I've even used half-and-half or heavy cream instead of regular milk in the past, resulting in a richer and creamier casserole. The beauty of cooking is in its adaptability, and this recipe readily embraces that spirit.

The finished product is a golden-brown masterpiece. The top is beautifully browned, the interior is perfectly cooked and moist, and every bite is a symphony of flavors and textures. The caramelized onions provide a delightful sweetness that cuts through the richness of the cheese and cream, while the spinach adds a touch of freshness. It's a casserole that's as visually appealing as it is delicious.

Beyond its deliciousness and ease of preparation, this savory French toast casserole is also incredibly adaptable to different dietary needs. For a vegetarian option, simply omit the cheese. For a vegan version, you can use a plant-based milk and egg substitute. You can also adjust the ingredients to suit your preferences. For instance, you could add some sun-dried tomatoes or roasted red peppers for extra flavor and color. Experimenting with different types of bread can also yield interesting results.

Step-by-step

• Heat 1 tablespoon of butter and oil in a large cast iron skillet over medium heat.
• Add the onions and let saute for 5 minutes, stirring as required.
• Add the thyme and sugar and continue to cook for 20-25 minutes on medium low heat. Be sure to stir the onions every 5 minutes so they caramelize evenly. If at any point the onions are caramelizing too fast, turn down the heat to the low setting.
• Add the balsamic vinegar to deglaze the pan, allow the onions to soak it all in.
• Remove the onions to a plate.
• While the onions are caramelizing, in a large bowl, whisk together the eggs, milk, crumbled feta cheese, and salt and pepper to preference.
• Set aside.
• Add the remaining 1 tablespoon of butter to the skillet.
• Add the garlic and allow it to saute for 30 seconds or until it becomes fragrant.
• Add the spinach and let it cook down until just wilted, about 1-2 minutes.
• Remove spinach to the same plate as the onions.
• Toss to mix evenly.
• Position a rack in the center of the oven and preheat the oven to 375°F if you are baking the casserole immediately.
• Generously spray a 9x13 baking dish with nonstick cooking spray.
• Add the diced french bread into the dish and press gently so the bread flattens a bit.
• Add the onion and spinach mixture on top, spreading it evenly.
• Using the back of a large spoon, press down the mixture down a bit so that it's not popping out over the dish.
• Pour the egg mixture over the prepared casserole.
• Sprinkle with the cheese and another small pinch of salt and pepper.
• Bake the casserole, uncovered, until the cheese melts, and the top gets all nice and golden, 45-50 minutes.
• Allow the casserole to cool for 10 minutes before slicing and serving.
