  1. When I went with TMI back in the 80’s and had KP duty, I put peanut butter in the baked oatmeal and it was an even bigger hit! Love TMI Baked Oatmeal! 🙂

  2. Hi Beth,
    Is there a way that I could get a copy of the Teen Missions cookbook. I cook for three week long mission trips each summer and would really like some large group recipes. I cook from anywhere from 100 to 250 for breakfast/dinner and have cooked to up to 900 for lunch. We have used prepacked ready to bake meals from Sam’s Club/Costco but I am really trying to save the ministry money by making meals from scratch. I would appreciate any help or advice I can get. Thanks!

  3. What happened to the entire TMI cookbook? Can it be purchased anywhere?

    My Mom used this recipe for several years as Head Cook at church camp in Northern Illinois. YUM! We would have eaten it everyday.
    She used a lot of recipes out of her Feeding The Multitudes cookbook from Teen Missions International.

    Im an FTMer, venezuela preteen 93′, venezuela 94′ and venezuela 96’…i was just telling my husband the other day that i still have not figured out how to make tmi’s baked oatmeal! Now i can…may seem like no big deal but seeing this recipie posted brought tears to my eyes! So many memories took me back. Thank you!

  6. You don’t say what size pan. someone mentioned a 9 x 13 pan, but I cannot imagine 15 cups of oats, 10 eggs, all that oil and milk will fit in one 9 x 13 pan!! Really?

    • Mary, We use the larger baking pans (industrialized size). You would need to cut the recipe down. If it says it will feed 30 and you want to only feed 6, then cut the amounts by 5.

  7. I made this a few weeks ago for the young men at a Boys Ranch I work at. When I told them what it wad noses curled up and eyes rolled. Most of the boys and staff took the min required serving…ALL of them took seconds, thirds and some had fourths. The have been asking ever since when I will be making it next. It’s on the menu for tomorrow 🙂

  8. I have not been out on a team in over 20 years but I still make baked oatmeal. It tastes great and brings back many wonderful memories. I love this recipe!

  9. This recipe worked great for us just as written. If you try it and it takes longer to bake, try using a bigger pan next time and spreading it a little thinner. If it doesn’t seem to serve 30, cut the pieces smaller and serve it with some fruit 🙂

  10. Does “tsp” refer to teaspoon or tablespoons? I realize this may sound like a funny question, but…
    Also, about how many servings does that recipe as written serve?

  11. It takes more like 45 minutes. Put 4 granny Smith apples in half that recipe and it fills a regular 9 by 13 pan. I add ten teaspoons of cinnamon also to make it better.
