A few months ago a reader named Amy sent me this recipe for Rosemary, Mushroom, and Chickpea Ragout served over toast, and I printed the recipe and added it to my big folder of “must cook” ideas. (Thanks Amy!) Then a few weeks later I was flipping through my friend Stephanie’s newest book 365 Slow Cooker Suppers and I noticed a slow cooker recipe with similar flavors. So you know where this is going don’t you? I combined ideas from both those recipes, plus a few thoughts of my own, and came up with this Slow Cooker White Bean, Mushroom, and Rosemary Spaghetti Squash Bowl. Jake and I loved this, and he also thought it was delicious served over rice if you’d prefer that to the spaghetti squash version. Whether you eat it on toast, over rice, or in a bowl with spaghetti squash, this mushroom and bean ragout is a satisfying blend of flavors.

This delicious and versatile vegetarian ragout is my Meatless Monday idea for this week, although I realize I am ignoring St. Patrick’s Day with that suggestion. If you’re celebrating the holiday I highly recommend Roasted Cabbage with Lemon as a delicious green option!

Cut one pound of brown Crimini (Baby Bella) mushrooms in thick slices, heat the oil, saute the mushrooms until they’re starting to brown and all the water has evaporated, and add mushrooms to the slow cooker. Add a little more oil to the pan and saute the onions until they’re starting to lightly brown on the edges.

While the mushrooms brown, wash and finely chop the rosemary. (If you only have dried rosemary, I would crush in a mortar and pestle.) Add garlic, rosemary, dried thyme, and black pepper to the onions and saute about 2 minutes more. Put the onion mixture in the slow cooker. Add one cup vegetable broth to the pan and simmer until it’s reduced to one-half cup. If you have some Better Than Bouillon Organic Mushroom Base (affiliate link) or another good qualilty mushroom base, I’d add a small amount of that to the stock for even more mushroom flavor, but it’s optional. (Edit: Shirley from Gluten Free Easily tells me that Better than Bouillon no longer guarantees their products are gluten-free, so that brand won’t work for people who have to avoid gluten.)

While the stock simmers, rinse the beans with cold water, drain, and add them to the slow cooker. Add the petite diced tomatoes with juice and reduced vegetable stock to the slow cooker and cook 3-4 hours on high.

About an hour before the beans will be done, cook the spaghetti squash. (You can cook the spaghetti squash in the slow cooker if you prefer, but I roasted mine.) Cut the squash lengthwise into four pieces and scrape out seeds, rub with a little olive oil, season with a little Italian Herb Seasoning (affiliate link) and roast at 400F for about 50-60 minutes, or until the squash is soft and shreds apart easily. When the squash is done, use a fork to scrape off the strands and divide into four serving bowls.

By now the ragout is done, with lots of flavorful liquid to season the spaghetti squash. Fill a bowl with squash, leaving a spot in the middle to fill with one-fourth of the ragu mixture.

Serve with a generous amount of Parmesan cheese, preferably shaved pieces of Parmigiano Reggiano if you have some. Enjoy!

Slow Cooker White Bean, Mushroom, and Rosemary Spaghetti Squash Bowl We loved this delicious Slow Cooker White Bean, Mushroom, and Rosemary Spaghetti Squash Bowl! Ingredients: 1 lb. brown Crimini mushrooms (also called Baby Bellas) washed and thickly sliced

2 tsp. + 2 tsp. olive oil

1 large onion, chopped in 1/2 inch pieces

1 T garlic paste or finely minced fresh garlic

2 tsp. finely chopped fresh rosemary leaves

2 tsp. dried thyme

fresh ground black pepper to taste

1 cup vegetable broth, simmered to reduce to 1/2 cup

1/2 teaspoon Better Than Bouillon Organic Mushroom Base or other high-quality mushroom base (optional, but it does add to the mushroom flavor)

1 can (15 oz.) white beans of your choice, rinsed well with cold water and drained

1 can (14.5 oz.) petite diced tomatoes plus juice Spaghetti Squash Ingredients: (This can also be served over toast or cooked rice)

1 large spaghetti squash

1 tsp. olive oil for brushing squash

1 tsp. Italian herb blend Directions: Wash mushrooms and cut into thick slices. Heat 2 teaspoons olive oil in a large frying pan over medium high heat and saute mushrooms until they’re starting to brown and all the liquid has evaporated, about 4-5 minutes. Add mushrooms to the slow cooker. Heat 2 more teaspoons oil in the same pan, add chopped onions and saute until they’re starting to brown, about 4 minutes. Add the garlic paste or minced garlic, chopped fresh rosemary, dried thyme, and a generous amount of fresh ground black pepper and saute about 2 minutes more. Add the onion mixture to the slow cooker. Put 1 cup vegetable broth into the pan you sauteed the vegetables in and simmer over medium heat until it’s reduced by half. (Stir in a small amount of mushroom base (affiliate link) for extra flavor if you have some.) While the broth reduces put the beans into a colander placed in the sink and rinse well with cold water (until no more foam appears) then let drain. Put the reduced vegetable broth, drained beans, and tomatoes (with juice) into the slow cooker. Cook on high for 3-4 hours or on low for 6-8 hours. If you want to cook the spaghetti squash in the slow cooker, start it in another slow cooker at the same time you start cooking the ragout, but I roasted my squash. Preheat oven to 400F/200C. Cut the squash lengthwise into four pieces and scrape out the seeds and discard them. Mist or brush the top of the squash with olive oil and season with Italian Herb Seasoning (affiliate link). Place the squash on a baking sheet that you’ve sprayed with non-stick cooking spray or olive oil and roast 50-60 minutes, or until the squash pulls apart easily into strands. When the ragout is done, shred the squash apart with a fork and divide among 4 servings bowls, leaving a space in the center for the ragout. Put one-fourth of the ragout mixture over the squash in each bowl and serve hot, with freshly shaved or grated Parmesan cheese if desired.This will keep for several days in the fridge and can be reheated in a microwave or on the stove. The ragout mixture freezes well. Notes: Equipment:

I used my Crock-Pot 3-1/2-Quart Slow Cooker (affiliate link) for this recipe, and it could have even been a little smaller. If you only have a big slow cooker I’d double the recipe and freeze some of the ragout for another meal. This recipe was adapted from this recipe for Rosemary, Mushroom, and Chickpea Ragout and a recipe for Mushroom and Bean Ragout in 365 Slow Cooker Suppers.
