Step by Step Method

Instructions for making the mashed potatoes are at the bottom

Step 1

Grease a 9x13 casserole dish. Preheat oven to 375° F (190° C).

Step 2

In a skillet over medium heat, saute the onions with 1/4 cup butter, 1/2 salt and pepper until the onions are brown and soft (around 10 minutes or more).

Step 3

Place a single layer of cooked lasagna noodles in the bottom of the casserole dish. Evenly spread 1/2 of the mashed potato on top of the noodles. Spread 1/2 of the cooked onions on top of the potatoes, then sprinkle 1 cup of the shredded cheese.

Step 4

Repeat layers once more, then top with a final layer of noodles and the remaining 1 cup of cheddar cheese.

Step 5

Bake for 30 minutes, or until the top is golden and bubbly.


Step 6

Put cut potatoes into a large pot and cover with water. Boil until the potatoes are soft when poked with a fork. Drain water.

Step 7

Add in cream, sour cream, butter, salt, pepper and garlic powder. Mash and stir until smooth and well-blended. Add more salt and pepper if desired.
