Instructions
Preparation
- Preheat oven to 375°F. Line a loaf pan with parchment paper and oil the narrow ends.
- Toast the walnuts in an extra-large skillet over medium-low heat until golden and fragrant, about 8-10 minutes. Set aside. (Alternatively, toast on a sheet pan in a 350°F oven for 15-16 minutes.)
Cook Vegetables
- In the same extra-large skillet, heat oil over medium heat. Sauté the onion for 2-3 minutes, then add celery and carrots, and sauté for 5-6 more minutes until they begin to soften.
- Add mushrooms, garlic, salt, pepper, and sage. Cover with a lid and sauté until mushrooms release their liquid, 10-15 minutes. Remove the lid and continue cooking until all liquid has evaporated.
- Feel free to deglaze with a splash of wine if desired, cooking it all off. The mixture should be quite dry when done—you'll know you're close when the mushrooms begin sticking to the pan.
- Turn off the heat and stir in the miso paste, mixing until well combined.
Assemble and Bake
- In a food processor, pulse the walnuts into lentil-sized pieces. Transfer to a large bowl.
- Pulse the mushroom mixture in the food processor, leaving a little texture. Add to the bowl with the walnuts.
- Stir in the mustard, eggs, and oats. Add cottage cheese and/or grated cheese if using, and give a good stir.
- Pour the mixture into the prepared loaf pan and place on the middle rack of the 375°F oven for 35-45 minutes. Check at 30 minutes and rotate if needed.
- The loaf is done when slightly puffed and the internal temperature reaches 165°F. (Adding cottage cheese may increase baking time by 10-15 minutes.)
Finishing
- Let the loaf rest for 5 minutes before flipping onto a platter. Loosen the edges with a knife, or keep it warm in the loaf pan covered with foil until serving.
- Serve with mushroom gravy and garlic mashed potatoes. Optional: drizzle with gravy and sprinkle with pomegranate seeds and fresh sage leaves.
Notes
- Try pairing with a rich mushroom gravy for extra flavor.
- Leftovers can be reheated or enjoyed cold as a vegetarian sandwich filling.
- You can prepare the mixture ahead of time and bake when ready to serve.
