Enchilada Sauce

  • 800 g / 28oz crushed canned tomato
  • 1 tbsp olive oil
  • 1 clove garlic , whole peeled
  • 1/2 red onion , chopped
  • 1 cup fresh coriander / cilantro , lightly packed
  • 1 tbsp EACH cumin , oregano and paprika (any type)
  • 1 tsp EACH salt , garlic powder, cayenne pepper (optional) and sugar (any)
  • 2 tsp coriander powder
  • Black pepper

Hot Filling

  • 1 tbsp olive oil
  • 1 garlic clove , minced
  • 1/2 red onion , finely chopped
  • 1 large red capsicum / bell pepper , chopped (~1 1/2 cups)
  • 2 zucchinis , chopped (~1 1/2 cups)


  • 425 g / 14 oz can black beans , drained and rinsed
  • 1 1/2 cups frozen corn
  • 6 large flour tortillas (approx 22 cm / 9" wide) (2)
  • 2 1/2 cups / 200g grated melting cheese (I used low fat cheddar)
  • Fresh coriander / cilantro leaves , for garnish (optional)


  • Preheat oven to 180C/350F.
  • Place Enchilada Sauce ingredients in a blender and whizz until onion is whizzed in and no longer visible. (In my Vitamix, I started on 3 then cranked it to 8 and it took 15 seconds)
  • Heat oil in a large non stick skillet. Add garlic and onion, cook for 1 minute. Add capsicum, cook for 1 minute. Add zucchini and cook for 3 minutes until charred. Remove skillet from heat.
  • Smear a bit of Enchilada Sauce on the bottom of a casserole dish. Place 1 tortilla in the middle, then tear on in half and place on either side (see step photos or video).
  • Top with half the Hot Filling. Scatter over half the black beans, half the corn. Drizzle over 1 cup Enchilada Sauce and 3/4 cup grated cheese.
  • Repeat with another layer so you have 2 layers of filling. Then for the last layer, top with tortillas then cover 2 cups of Enchilada Sauce (Note 3) and scatter over remaining cheese.
  • Bake for 25 minutes or until cheese is bubbling and golden. Stand for 5 minutes, then garnish with fresh coriander and serve.


1. My casserole dish is 30 x 25 x 6 cm / 12 x 10 x 2.5 inches, 18 cup volume.
2. You can use corn tortillas if you prefer, but I find flour is more similar to actual lasagna.
3. This makes about 5 cups of Enchilada Sauce but I find the tortillas were a bit too soggy for my taste if I used it all. So I use 1 cup for each of the layers, then 2 cups for the topping. Make a quick soup with the leftovers or use it as a Sauce (see below for more ideas!)
4. Difference between this fresh Blender Enchilada Sauce and a stovetop one (like in my Beef Enchiladas) - Flavour wise, this is much fresher and has stronger spices, coriander / cilantro and garlic flavours compared to a traditional stovetop version. This sauce has stronger flavour because it is the seasoning for the vegetables. In comparison, the beef in my Beef Enchiladas are seasoned when cooked. So the Enchilada Sauce seasoning isn't as strong.
5. Other uses for this Blender Enchilada Sauce: Definitely traditional enchiladas! Toss a bit of chicken and veggies in this sauce, roll up then top with this Blender Enchilada Sauce, cheese then bake until bubbly. :-) It also makes a fantastic soup base. Saute some garlic, onion and veggies, add the Blender Enchilada Sauce plus some chicken stock / broth for more depth of flavour. I also use it as a salsa to serve on the side of tacos, fajitas, in burritos.
