Montana Mountain Casserole
Today’s recipe is a meaty dish that is comfort in a bowl. With bacon, sausage, pork and chicken there is meat in every bite. My boys took this down to china town. They loved it. The herbs and sausage flavor everything so nicely. Make it fast in the Instant Pot or let it simmer for hours in the slow cooker. (This recipe is adapted from Mountain Cassoulet on The Taste of Montana.)

Add in the smoked sausage and brown it in the bacon grease for 2-3 minutes. Add in the onion and celery and saute for 2 minutes. Stir in the garlic.

Pour in the broth and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot.
Stir in the pork, chicken, beans, carrots, bay leaf, thyme, rosemary, oregano, marjoram, basil, tarragon, fennel, salt and pepper.

Ladle into bowls and serve.

Notes/Tips
- Serve with a crusty baguette or cornbread and a side salad.
- This recipe is gluten free and dairy free.
- If you have Herbes de Provence it makes a great substitute for all the herbs/spices. I didn’t have it and couldn’t find it at the store so I went with the array of seasonings in my cabinet.
- Try adding in some chopped kale for more color and nutrition.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
- Other recipes you can make with boneless chicken thighs are Sierra’s Casserole and Brokenhearted Chicken.

This is delicious and was loved by the whole extended family! I doubled it and cooked it in my 8qt.
Thanks Louise for the 5 stars!
Karen, this recipe sounds very hearty! I love the big chunks. I would like to double the recipe. Will a double recipe fit in my 6-quart Instant Pot? Should I do the browning step in a wok or large skillet or a saucepan? You continue to amaze me with the variety in the recipes you send us. Thank you for your hard work!
Yes it will fit in a 6 quart. And I bet browning would be easier on the stovetop!
Ooooooh! My carnivorous cave man is gonna love this one! Got one question. You said we could sub Herbs de Provence for the other herbs you have listed. How much Herbs de Provence would I use in place of all the others? Thanks. I will be back with stars.
I would start with a tablespoon and if you want to add more at the end you can.
Thanks, will do that & let you know how it goes.
