1️⃣ Prepare the Mashed Potatoes

• If using homemade mashed potatoes, prepare them first.
• If using instant or store-bought, measure out 3 cups.

2️⃣ Cook the Filling

• Heat olive oil in a large skillet over medium-high heat.
• Add onions & celery, sauté for 3 minutes.
• Stir in garlic and cook for 1 more minute.
• Increase heat to high and add ground beef. Cook until browned, breaking it apart.
• Drain excess grease and reduce heat to medium-high.
• Sprinkle in flour and mix well. Add tomato paste & thyme, stirring for 1-2 minutes.
• Deglaze the pan with chicken broth, scraping up brown bits for extra flavor.
• Stir in ½ of the brown gravy and frozen vegetables. Cook until heated through.
• Season with salt & pepper, adding more gravy if desired. Remove from heat.

3️⃣ Assemble the Shepherd’s Pie

• Preheat broiler to 550°F (or high).
• Transfer beef mixture to a lightly greased 9-inch pie pan or 7×11 casserole dish.
• Carefully spread warm mashed potatoes over the filling.
• Use a fork to create texture on top (helps with browning).

4️⃣ Broil & Serve

• Place dish 5 inches from broiler and cook for 5 minutes (watch closely after 2 minutes!).
• Once the top is golden brown, remove from heat.
• Let cool slightly, then serve warm! 😋
