Let’s get cooking, shall we? Follow these steps to create your own delightful Keto Casserole Recipe:

1. Preheat your oven to 180°C (350°F). It’s the perfect time to enjoy the anticipation of a meal coming together.

2. Heat olive oil in a large skillet over medium heat. Add the chopped onion and minced garlic, sautéing until the onion is translucent — a familiar, comforting scent that always reminds me of home.

3. Add the ground meat to the skillet, cooking until browned. Stir in the diced bell pepper, sliced zucchini, and mushrooms, cooking for about 5-7 minutes until tender. Sprinkle with salt, pepper, and thyme.

4. Stir in the spinach leaves until wilted, then pour in the heavy cream, allowing it to simmer and thicken slightly. This creamy base is what dreams are made of, a nod to the rich stews of my childhood.

5. Transfer the mixture to a baking dish, smoothing it out evenly. Top with shredded cheese, and don’t forget to sprinkle a dash of cinnamon — my secret ingredient that adds warmth and depth.

6. Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden. This is when the magic happens, as the flavors meld together into a harmonious symphony.

7. Allow the casserole to cool slightly before serving. This wait is the perfect moment to set the table and pour yourself a cup of tea, just like mum used to.
