Here is what I served for a recent meal when we had 12 guests.
Easy
crock pot beef tips - except I baked ours in a Dutch oven in the regular oven- doubled the recipe
Make ahead mashed potatoes - this recipe does not use cream cheese like most make ahead recipes call for - also doubled this recipe
Baked carrots
Green beans
Worlds Best Dinner Rolls - I followed the recipe exactly except I mixed them all by hand in a Tupperware fix and mix bowl. The recipe says to shape the dough into 24 rolls but I made them a regular dinner roll and had about 40. At 24, they would be very large rolls I think, more like a jumbo sandwich bun.
Dessert was fresh fruit -a Georgia seedless watermelon, red grapes, strawberries and fresh pineapple-and a bag of Chips Ahoy cookies I got on sale for 99 cents.
I usually bake a dessert or 2 but my husband and I have not been eating dessert for about 2 months and with all the other cooking, I just didn't feel like baking a dessert too. Unfortunately, 3 of the guests were disappointed with my baking slack off. They did not leave hungry though, they just ate extra rolls and watermelon.
Beverages were plain and sweet tea.
I recommend all of the recipes. And that is one of the ways I feed a crowd.
