Imperial, California - Just because you aren’t in the mood for meat doesn’t mean you have to miss out on one of the best comfort foods around. In this vegetarian meatloaf, savory portobello mushrooms play the part of the meat - and play it well, providing a wonderful meat-like texture. This recipe goes beautifully with traditional meatloaf side dishes, like mashed potatoes and creamed Brussels sprouts. Or, mix things up a bit and serve it alongside a pile of baked sweet potato fries.

Makes 6 servings



  • Cooking spray
  • 1 red bell pepper
  • 1 green bell pepper
  • 2 lbs portobello mushrooms, gills removed
  • 1 tbsp olive oil
  • 1 cup green beans, chopped into ½” pieces
  • 1 cup carrots, peeled and coarsely chopped
  • ½ cup red onion, chopped
  • 1 cup walnuts, chopped and toasted
  • 1 cup panko breadcrumbs
  • 2 tbsp fresh basil, chopped (or 1 tbsp dried)
  • 2 tbsp fresh thyme, stems removed (or 1 tbsp dried)
  • 1 tbsp tomato paste

  1. Spray a 9 x 12-inch loaf pan with cooking spray.

  3. Reduce the oven temperature to 350°. Process mushrooms in a food processor until finely chopped. Heat olive oil in a large nonstick skillet over medium-high heat, then add the mushrooms and sauté until the liquid evaporates (about 15 minutes). Add the mushrooms to the bowl with the peppers.
  4. Sauté the green beans, carrot, and onion for six minutes or until crisp-tender. Add this mix to the bowl of mushrooms and peppers.
  5. Stir in walnuts, panko, basil, thyme, tomato paste, Dijon mustard, salt, pepper, cheese and eggs. Mix well.
  6. Scoop mixture prepared loaf pan. Bake at 350° for 45 minutes.
  7. To make the glaze, combine tomato paste, vegetable broth, and Dijon mustard. Brush mixture on top of the mushroom loaf at the end of the 45-minute cook time, then bake for another 10 minutes.
