CHEF JENN’S TIPS

• You can substitute cheddar cheese with Parmesan cheese, white cheddar, or marble cheese. 
• Warm the mashed potatoes to spread them more easily. Just a few minutes in the microwave will do the trick. 
• You can add other leftover veggies like asparagus, broccoli, corn, mushrooms, and zucchini. 
• You can use a gravy mix instead of leftover gravy. Prepare it according to the package directions.
• If you’re using fresh carrots, peel them, slice them thin, and parboil for 3 minutes in salted water.
• You can substitute the dehydrated garlic for ½ teaspoon of garlic powder and 1 teaspoon of onion powder instead of dehydrated onion.

MAKE IT A MEAL

This comforting dish is a meal all on its own! You can pair it with some tasty nibbles like garlic bread or Yorkshire pudding. A light side, like a classic Caesar Salad or garden vegetable salad with Balsamic Dressing, always goes well with Shepherd’s Pie. If you’re itching for a dessert, serve these Smoked Peaches; they’re simple to make. And to drink? Try this floral Lavender Spritz cocktail.
