This is a basic recipe. You can use it as the basis of a meat loaf and add any type of additional ingredients you desire.
2 beaten eggs
¾ c milk (you can omit this for a drier loaf)
2/3 c bread crumbs or crushed crackers
2 T grated onion
pinch of salt and pepper
1 ½ lbs ground beef
2 T catsup or BBQ sauce
¼ catsup
2 T brown sugar
1 t dry mustard
Combine all ingredients, except those for sauce, in a large bowl and mix well. Place in a loaf pan for baking in the oven or a round baking dish for the microwave. If you microwave, use a small glass to leave the center of the loaf open (this will decrease cooking and increase uniformity doneness). Bake at 350°F for 1 hour, mix sauce and cover, baking an additional 15 minutes; or microwave 20 minutes on medium-high, turn and finish another 5-10 minutes with sauce on top.
