How to Make Cheesy Bacon & Beef Shepherd’s Pie

1. Prepare the oven & dish: Preheat your oven to 350 F and grease a 2-quart baking dish.
2. Cook the bacon: In a skillet over medium heat, cook the diced bacon until crispy. Remove and drain on paper towels. Set aside.
3. Brown the beef: In the same skillet, cook the ground beef in the bacon drippings until browned. Stir occasionally to break up any chunks. Sprinkle in the flour, mix well, and cook for 1 minute.
4. Add vegetables & seasonings: Stir in the onion, mushrooms, carrot, and celery. Pour in the beef broth and Worcestershire sauce. Add thyme and black pepper. Bring to a boil, then reduce heat and let simmer uncovered for about 15 minutes until the vegetables are tender. Stir in the cooked bacon and transfer everything to the prepared baking dish.
5. Prepare the mashed potato topping: Mix the hot mashed potatoes with 1/2 cup of shredded cheese. Spread the mixture evenly over the beef filling. Sprinkle the remaining 1/4 cup of cheese on top and finish with a dash of paprika.
6. Bake & broil: Bake, uncovered, for 20-25 minutes until heated through. For a golden, crispy top, broil for a few minutes before serving.

Recipe Variations & Substitutions

• Swap the protein: Try ground turkey, chicken, or even lentils for a lighter or vegetarian option. Or make a classic shepherd’s pie with ground lamb.
• Make it dairy-free: Use dairy-free cheese and plant-based butter in the mashed potatoes.
• Add more veggies: Mix in peas, corn, or bell peppers for extra texture and nutrients.
• Try a different cheese: Experiment with gouda, Monterey Jack, or parmesan for a unique twist.

How to Store

• Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days.
• Freezing: Shepherd’s pie freezes well! Wrap it tightly and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
• Reheating: Warm leftovers in the oven at 350 F for about 20 minutes or microwave in 1-minute intervals until heated through.
