Ingredients

Scale

Vegetables

  • 2 tsp Italian herb blend
  • 1 tbsp tomato paste
  • 1 cup finely chopped broccoli florets (about 80g)
  • 1 1/2 cups finely minced spinach (about 80g)
  • 1 tsp olive oil or avocado oil (for sautéing)
  • 1/2 cup small diced sweet potato (about 60g)

Oatmeal Base

  • 1 tsp baking powder
  • 2 cups whole milk
  • 2 cups rolled oats (200g, not instant)
  • 1 large egg, beaten
  • 1 tsp olive oil or avocado oil (for greasing the baking dish)

Instructions

  1. Preheat the Oven and Prepare Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9-inch square baking dish with 1 tsp olive oil or avocado oil, or line it with parchment paper for easy removal and cleanup.
  2. Cook the Vegetables: Heat 1 tsp olive oil or avocado oil in a skillet over medium heat. Add the finely minced spinach, chopped broccoli florets, and diced sweet potato. Sauté for 4-5 minutes until vegetables soften. Stir in the Italian herb blend and tomato paste, cooking for another 2 minutes until well combined. Remove from heat and let cool slightly.
  3. Mix Oats, Egg, Milk, and Baking Powder: In a large mixing bowl, combine the rolled oats, baking powder, whole milk, and beaten egg. Stir until the mixture is well combined, creating the oat base that will bind the bake together.
  4. Combine and Rest the Mixture: Add the cooled cooked vegetables to the oat mixture. Stir thoroughly until evenly incorporated. Let the mixture sit for 5-10 minutes so the oats absorb some liquid and soften, ensuring the bars hold together after baking.
  5. Bake and Cool: Pour the mixture into the prepared baking dish and press down evenly. Bake for 30 minutes or until the oats are set and firm to the touch and all liquid has been absorbed. Allow to cool completely before slicing to produce clean, tidy bars.

Notes

  • Use rolled oats (old-fashioned oats) for the best texture; avoid instant or steel-cut oats as they do not perform well in baking.
  • Pre-cook vegetables by sautéing to prevent crunchy, undercooked pieces in the final bake.
  • If mixture looks dry before baking, add a splash of milk to maintain moistness as oats absorb liquid during baking.
  • For extra flavor, toast dry oats with Italian seasoning in a skillet before mixing.
  • To make vegan, substitute the egg with a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water, rested 5 minutes).
  • Substitute milk with plant-based milks like oat, almond, or soy for dairy-free options; note texture and creaminess may vary.
  • Store leftovers in an airtight container in the fridge for up to 5 days or freeze in portioned squares for up to 3 months.
  • Reheat refrigerated portions in the microwave for 1-2 minutes, frozen portions for 2-3 minutes, or warm in a preheated 350°F oven for about 10 minutes.
