Ingredients
- 1 lb. brown Crimini mushrooms 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
- 1 can white beans of your choice, rinsed well with cold water and drained
- 1 can petite diced tomatoes plus juice
- 1 large spaghetti squash
- 1 tsp. olive oil for brushing squash
- 1 tsp. Italian herb blend
Directions
- Rinse the mushrooms, then slice them thickly. Warm 2 teaspoons olive oil in a large skillet set over medium high heat, add the mushrooms, and cook until their moisture has cooked away and the edges begin to color, about 4-5 minutes. Transfer the mushrooms into the slow cooker.
- Pour another 2 teaspoons oil into that same skillet. Stir in the chopped onions and cook until they begin to take on a little color, about 4 minutes. Add the garlic paste or minced garlic, fresh rosemary, dried thyme, and plenty of fresh ground black pepper, then cook for about 2 minutes longer. Scrape this onion mixture into the slow cooker with the mushrooms.
- Pour 1 cup vegetable broth into the skillet you used for the vegetables. Simmer it over medium heat until the amount is reduced by half. If you have mushroom base, stir in a small spoonful for deeper flavor.
- As the broth cooks down, set the beans in a colander in the sink. Rinse them thoroughly with cold water until the foam is gone, then leave them to drain.
- Add the reduced broth, the drained beans, and the tomatoes with their juice to the slow cooker. Set it to high for 3-4 hours, or use low for 6-8 hours.
- If you prefer making the spaghetti squash in a slow cooker, get it going in a separate slow cooker when the ragout starts. For roasted squash, heat the oven to 400F/200C. Slice the squash lengthwise into four pieces, scoop out the seeds, and throw the seeds away.
- Brush or mist the cut surface of the squash with olive oil, then sprinkle it with Italian herb blend.
- Set the squash on a baking sheet coated with non-stick cooking spray or olive oil. Roast for 50-60 minutes, until the flesh separates easily into spaghetti-like strands.
- Once the ragout has finished cooking, use a fork to pull the squash into strands. Divide the squash among 4 serving bowls, making room in the middle for the ragout. Spoon one-fourth of the ragout over each bowl of squash and serve hot, adding freshly shaved or grated Parmesan cheese if you like.
- Leftovers keep for several days in the refrigerator and can be warmed in the microwave or on the stovetop. The ragout also freezes nicely.
