What Makes This Lentil Mushroom Stew Iron-Rich and Nourishing

As a busy woman myself, I know how important it is to nourish our bodies with the right nutrients. This lentil mushroom stew is a fantastic source of iron, which is essential for energy levels and overall health, especially for women and children. I want you to feel empowered and energized, and this stew is a delicious way to do just that. So let’s get cooking and nourish ourselves and our loved ones with this wholesome, flavorful meal, a delicious lunch choice!

Choosing the Best Lentils for Your Stew

When it comes to lentils, there are so many varieties, but which ones work best in this stew? I recommend using green lentils for this recipe. They hold their shape well during cooking and have a slightly peppery flavor that complements the mushrooms perfectly. Brown lentils are another good option, though they tend to become a bit softer. Red lentils, on the other hand, cook quickly and become quite mushy, so I’d avoid them for this particular stew. Texture is key, and green lentils strike that perfect balance between tenderness and firmness.

Selecting Your Mushrooms

Mushrooms add a depth of flavor and a hearty texture to this stew. I prefer using cremini mushrooms, also known as baby bellas, because of their rich, earthy taste. Button mushrooms are also a great choice and are more readily available. Other options include shiitake or oyster mushrooms for a more unique flavor profile. To prepare the mushrooms, simply slice them evenly and sauté them until they are tender and slightly browned. This brings out their natural umami and adds a delicious layer to the stew.

  • 2-4 Tbsp unsweetened almond milk or vegetable broth (for added moisture)
  • 1 Tbsp water ((or avocado or olive oil))
  • 1/2 cup chopped shallot

How to Make Lentil Mushroom Stew: Step-by-Step

Alright, let’s get into the step-by-step instructions. Trust me; it’s easier than you think!

  1. Heat a large rimmed pan over medium heat. Once hot, add oil or water and shallot and sauté for 2 minutes, stirring occasionally.

Step 1: Sautéing Shallots

  1. Add mushrooms and coconut aminos and increase heat to medium-high. Sauté for 5 minutes, stirring frequently. Add a pinch of salt and pepper.

Step 2: Sautéing Mushrooms

  1. Add thyme, lentils, and 2 cups vegetable broth (480 ml // or the smaller end of the range if adjusting recipe size). Bring to a low boil over medium-high heat. Once boiling, reduce heat to a simmer and cook on low for about 20 minutes, adding more broth as needed if the mixture looks dry. Adding the thyme at this stage allows its aromatic oils to infuse the entire stew, creating a richer flavor.

Step 3: Adding Lentils and Thyme

  1. In the meantime, add potatoes to a large pot and cover with water so they are just submerged. Bring to a boil on high heat and cook for 12-15 minutes or until they slide off easily when pierced with a knife.

Step 4: Boiling Potatoes

  1. Once tender, drain potatoes and add back to pot or a mixing bowl. Season with salt, pepper, and a bit of olive oil and mash until tender and fluffy. For added moisture in place of oil, add unsweetened plain almond milk or vegetable broth.

Step 5: Mashing Potatoes

  1. Once lentils are tender, taste sauce and adjust flavor as needed, adding more salt or coconut aminos for saltiness, pepper for spice, or tomato paste for more depth of flavor (optional – we didn’t find it necessary). Turn off heat and let the mixture rest so flavors can deepen. Add the 2 Tbsp (30 g // or more as needed) mashed potatoes to the lentil mushroom stew and stir in to thicken.

Step 6: Thickening the Stew

  1. To serve, divide mashed potatoes between serving plates or bowls and top with desired amount of lentil and mushroom gravy. Garnish with fresh parsley, vegan parmesan cheese, or more thyme, if desired.

Step 7: Serving the Stew

  1. Store leftovers separately, covered, up to 4 days in the refrigerator or in the freezer up to 1 month. Reheat on the stovetop or in a 350 degree F (176 C) oven until hot.

Tips for the Best Flavored Lentil Mushroom Stew

Want to take your stew to the next level? Here are a few tips:

  • Bloom the Thyme: Sautéing the thyme in oil (or water) for a minute before adding the other ingredients helps release its essential oils, intensifying the flavor.
  • Use High-Quality Vegetable Broth: The broth is the base of the stew, so using a good quality one will make a big difference in the overall taste.

Common Mistakes to Avoid

We all make mistakes in the kitchen, but here’s how to avoid some common pitfalls with lentil stew:

  • Lentils are mushy: Avoid overcooking the lentils by checking them frequently and simmering on low heat.
  • Stew is bland: Don’t be afraid to season generously with salt, pepper, and other spices. Taste as you go and adjust accordingly.
  • Stew is too watery: If your stew is too thin, simmer it uncovered for a bit to allow some of the liquid to evaporate. Alternatively, adding a bit of mashed potatoes will also thicken it up.
