This is an amazing dish! My mother-in-law makes this all the time for her sons and have gotten her daughters-in-law hooked on it. It's very easy to make but also VERY unhealthy...but sooo good.
3 sticks of butter (I know...I said it wasn't healthy)
8-9 medium potatoes
3 medium onions
1 lb. Velveeta Cheese
1 lb. bowtie noodles
Cook potatoes like you would for mashed potatoes. Cook bowtie pasta as directed on box. Saute onions in one stick of butter (again...I told you it wasn't healthy). Mash the potatoes using one stick of butter and 3/4 of Velveeta.
Spray 9x13 pan with Pam or other cooking spray (I use Favorite Thing #4 - Misto filled with olive oil)
Put the cooked bowtie pasta in bowl and butter with one stick of butter.
Layer 9x13 with noodles, then layer with mashed potatoes. Spread onion mixture on top of potatoes. Put the rest of Velveeta in small cubes on top of onions.
Cover with foil and bake at 350 degrees for 30-40 minutes. Enjoy!!!
