Reviews for Shepherd's Pie Casserole
"This was delicious. The change I made was using the whole can of tomato paste and half a cup of horseradish and about 1tbsp mustard .for the veggies I used a can cream corn and some peas and carrots so I omitted the peppers and forgot to buy mushrooms!"
"Great comfort food!"
"SO easy and SO delicious!! This is a perfect fall/winter meal and can be adjusted to be made lighter and healthier. Extra lean ground beef and low fat cheddar cheese. I didn't use the egg as it just doesn't sound right to me."
"This recipe was fantastic! So delicious and flavorful! I added more potatoes and mushrooms to put the casserole into a 13 in. x 7 in. casserole dish. Amazing dish!"
