Introduction: Ratatouille Lasagna With Basil Walnut Pesto
I had no idea how much my world would change after having a baby. I was battling through postpartum and dietary restrictions while nursing did not make it any easier! As if this was not enough, I had an unbelievably strong craving for lasagna which, unfortunately, calls for tomato sauce - another strict no-no in my nursing diet :( I decided to go ahead and try making lasagna without tomatoes and see what happens. You know, just for fun :) Fortunately, I was able to tolerate other night shade vegetables.
Finally here it is - ratatouille lasagna without tomatoes, onions or garlic. Not only is it yummy, but it's super nutritious with all the vegetables and the protein coming from the cheeses :D
Supplies
Equipment:
- 9x13 baking dish
- Saute pan + spatula for making the ratatouille
- Mixing bowl + spoon for making the ricotta filling
- Large pot to boil lasagna noodles
- Oven to bake the lasagna in
For Ratatouille:
Dried herbs:
- Red chili flakes - 1/2 tsp (or more for some extra heat)
- Black pepper - 1/2 tsp
- Marjoram - 1/2 tsp
- Savory - 1/4 tsp
- Rosemary - 1/2 tsp
- Sage - 1/2 tsp
- Basil - 1/2 tsp
- Thyme - 1/4 tsp
- Oregano - 1/2 tsp
- Parsley - 1/4 tsp
Vegetables:
- Aubergine - 1/2 of a medium sized one
- Kale - 2 stalks
- Zucchini - 1 and 1/2
- Yellow squash - 1 and 1/2
- Yellow bell pepper - 1
- Orange bell pepper - 1
- Red bell pepper - 1
- Optionally can add 1/2 a red onion
Others:
- Olive oil - 4 tsp
- Salt - 1 and 1/2 tsp
For Ricotta filling:
- Whole milk ricotta cheese - 1 cup
- Salt - 1/4 tsp + pinch more
- Black pepper - 1/4 tsp
- Ground nutmeg - 1/4 tsp
- Fresh basil - 4 to 5 leaves, chopped
For Lasagna:
- Lasagna noodles of choice - 9 noodles (just make sure they're not the no-boil kind since this recipe doesn't have a liquid sauce)
- Vegetarian mozzarella or any other cheese of choice - 3 cups
- Vegetarian parmesan - 2 tbsp for garnish
- Water for boiling
For Pesto:
- Fresh basil - 3 cups, loosely packed
- Walnuts - 1/2 cup
- Vegetarian parmesan or mozzarella or pepper jack cheese - 1/4 cup
- Olive oil - 2 tbsp
- Salt - 1/4 to 1/2 tsp
- Black pepper - 1/2 tsp
- Water - 1 tbsp (optional, but I like to use this for a skinny version of pesto)
Step 1: Prep the Vegetables
- Finely dice all the vegetables. It's important to keep the pieces small so it's easier to eat the lasagna later on :)
Step 2: Make the Ricotta Filling
- In a mixing bowl, add the ricotta cheese and mix until smooth and creamy
- Add salt, pepper, nutmeg and chopped basil and mix until incorporated. Set aside to use during assembly
Step 3: Make the Ratatouille
- On medium-low heat, add olive oil to a large saute pan. Once hot, add in all the herbs and saute until they turn aromatic
- If using onion, add them now and saute for 5 minutes until they turn translucent.
- Also give the kale a head start by adding it in next and sauteing for 2 to 3 minutes uncovered
- Next add all the diced vegetables and salt. Mix well to combine and cook covered for about 10-12 minutes. I like to keep adding the condensation on the lid back into the pan to help the veggies cook
- It's better to almost overcook the veggies so it's easier to use during assembly and eating
Step 4: Prep Noodles
Boil lasagna noodles according to the instructions on the box
Note: This recipe is suitable for pre-boiled lasagna noodles. The no-boil ones require a more liquid sauce.
Step 5: Make Pesto
- To a blender, add walnuts and blend to a fine powder
- Then add salt, pepper and cheese and blend again until incorporated
- Chop basil and add to the blender along with the olive oil. Blend until combined
- Optionally you can add water to help with the blending instead of oil to make a skinny version of pesto that's equally aromatic and delicious!
Step 6: Assemble the Lasagna and Bake It!
Now, the ratatouille we made is the sauce. It's going to replace the tomato sauce that we would use in a traditional lasagna :) Make sure the cheese you use has non-animal rennet or non-animal enzymes :)
- Start by adding a light layer of ratatouille to a lightly oiled 9x13 baking dish
- Add 3 lasagna noodles and spread half of the ricotta filling on top of them
- Add a generous amount of ratatouille on top
- Sprinkle as much or as little cheese as you like :)
- Repeat with the next 3 noodles to form another layer. Finish the ricotta filling here (you won't need it for the 3rd layer)
- Finally, place the remaining 3 noodles. But this time, spread pesto on the noodles with a spoon or by hand. Again use as much or as little as you like! :)
- Finally, top with some vegetarian parmesan cheese (make sure it doesn't have animal rennet)
- Preheat oven to 350F and bake the lasagna for 15 minutes or until the cheese has melted and turned slightly brown
- Let sit for 5 to 10 minutes before serving
- Bon Appetit!
