I have included a homemade onion soup seasoning mix that you can use for this recipe as well as other recipes what call for an onion soup mix. If you prefer to use a premade onion soup mix, it will work just great for this recipe as well, just be sure to look at the measurements. The only reason I make my own is because I try to limit the amount of salt and preservatives that I feed my family.

If you do not care for wild rice, you could certainly use all long grain rice for this recipe. I like to use a little bit of long grain mixed in with the wild rice just give it some balance. Since wild rice tends to maintain a bit of bite even when fully cooked, I like the soft long grain rice in there to vary the textures.

  3. chinamom3078 – I am a woman who loves Jesus who loved me first. Prone to wander and distraction is common for me as I seek to reflect Him in my daily life. I am wife, mom, and grandma who has lived on 3 continents in 26+ apartments, townhouses, military housing, suburbs and now a 200 plus year old farm house. Preparing and hosting meals for the hundreds who have passsed through our home has been a joy and blessing to our family as we listened and shared over meals, coffee, light nights and Bible studies. A rich life! I have reached the age to feel qualifies to be an ”older woman” (as in Titus) even though I feel far from old and have plenty of room to grow each and everyday. And my joy is to teach Bible studies and help train other women to lead well.
