Dutch ovens are among the greatest inventions ever created. They are so versatile and make food so yummy. I took a dutch oven cooking class awhile back and learned a lot. FYI NEVER use foil when cooking with your dutch oven.
1 lb ground beef
lasagna noodles UNCOOKED
2 cups Mozzarella cheese
1 large jar spaghetti sauce
1 container Ricotta cheese
1 soda can size of V8
Preheat your oven to 350. Cook ground beef and onion in the dutch oven on the stove. Remove meat mixture and set aside. Break your lasagna noodles to form a layer. Pour about half of the vegetable juice on top, then dollop the ricotta, half the meat and half the cheese, then pour sauce on top of that. then you will layer more noodles and more juice, ricotta, meat, cheese, sauce. Then put the dutch oven in the oven and let cook for about an hour. You can test it to see if it's done by poking a knife through the center. If the noodles give lots of resistance, you know it's not done.
*I love lasagna this way, it's different and super good. You could also make this on a campfire, super easy. Just remember to add about 12 coals to the top of your oven.
