Creating Mashed Cauliflower Shepherd’s Pie is simple if you follow these straightforward steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Cook the Cauliflower: Steam or boil the cauliflower florets until soft, about 10-12 minutes. Drain and let it cool slightly.
3. Prepare the Filling: In a large skillet over medium heat, sauté the diced onion and minced garlic until fragrant. Add the ground meat, breaking it apart, and cook until browned. Incorporate the mixed vegetables, tomato paste, Worcestershire sauce, thyme, rosemary, salt, and pepper. Cook for an additional 5-7 minutes until well combined.
4. Make the Cauliflower Mash: In a food processor or mixing bowl, blend the cooked cauliflower, butter, milk, garlic powder, salt, and pepper until creamy and smooth. If using cheese, fold it in at this stage.
5. Assemble the Pie: Spread the meat filling evenly in a baking dish. Layer the cauliflower mash on top, smoothing it out with a spatula. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and slightly crispy.

Following these steps will guide you in creating an incredible Mashed Cauliflower Shepherd’s Pie effortlessly.
