Zucchini Casserole

A flavorful and easy zucchini casserole with rice to use up some of those prolific zucchinis coming from gardens all summer long!! 
 
By using some of the summer’s best in season produce, the marriage of zucchini, tomatoes, and basil is a match made in heaven!
 
A tasty side dish, or an irresistible main dish with the addition of some ground sausage!  Either way, you can’t go wrong!

When the garden spews forth with mountains of zucchini, what is one to do?!  Make this gluten free zucchini rice casserole to start!!

I have been away in North Idaho escaping, enjoying the sun and relaxation.  Bliss.    I am always anxious to get back home though, and this time was no different.  I missed my family, and I missed my kitchen!!  Eating out with so many “no’s” on the list is a real pain, as I am sure many of you can relate.

I came back to even more zucchinis, and loads of beans…so look forward to some of my favorite recipes with these vegetables!

This recipe was one I used to use pre-allergy days.   I have to “Tessify” the majority of my old recipes, but that is the fun part….for me! 

I changed this one by adding some more spices, changing the cheese and changing to brown rice for more nutrition.  This one could easily make a good vegetarian meal with some additional protein, but my family uses it as a side dish some of the time too. 

Lots of people have tried this, and it always goes over well!

Pressure cooking brown rice for the zucchini casserole:

Have you ever used your pressure cooker for cooking rice?  It is a new found love of mine.  Best textured rice I HAVE EVER HAD!  I love brown rice again!  Here’s how I do it:

  1. Soak your brown rice in water and 2 tablespoons of apple cider vinegar for at least 12 or up to 24 hours.  I also add some sprouted brown rice flour to the water to assist in even MORE break down of the phytase.  I reserve a half of cup of this liquid to reuse every time, thereby increasing the amount of phytase I break down the next time I soak my brown rice.  By doing this, I can finally digest brown rise easier instead of being bloated and gassy!
  2. I have also use sprouted brown rice and skip the soaking!
  3. TO COOK:  Rinse your brown rice well.   Use 1 cup rice to 1 1/4 cups liquid.  Add in 1 tablespoon avocado oil, and 1/2 teaspoon sea salt per cup of rice.  Bring your pressure cooker to full pressure and cook for 18 minutes.  Turn off, and let it come down naturally for at least 10 minutes, or longer.  Then, remove lid and it is ready to go!

Making a complete meal out of this zucchini squash casserole:

We like to add a favorite cooked ground sausage to the mix to make this a main course with meat.

SO find a favorite ground sausage, cook it up, then add to the casserole mix prior to baking!

    My family loved this recipe! It was a big hit! We added ground beef to make it a main course. Great way to use zucchini from our garden. This will definitely become a repeat meal for us. I think it’s very adaptable to a variety of proteins. The flavors were so yummy!

    This looks great! I wanted to ask how to do a quick release of the pressure when pressure cooking brown rice? I’m new to pressure cooking, but would LOVE to make rice that way!
    Thank you!!

      quick release = run cold water over the top of the pressure cooker until it releases Cindy!
