Tips and Techniques for vegetable spaghetti/ Veggie spaghetti
What kind of pasta to use? I used spaghetti for this recipe, but you can use whatever pasta you prefer. Avoid angel hair pasta and thin pasta because they will become over-cooked and soggy.
Use non-stick pot- They can be bought online on Amazon and I highly recommend it over the regular stainless steel pressure cooker pot because it prevents sticking and burning.
Use unsalted butter– Because it prevents this meal from becoming too salty.
Fresh vegetables vs. Frozen veggies– Use a bag of frozen vegetables for a quick and convenient option but I always recommend fresh vegetables because it does not release a lot of water duding cooking.
Refrigerate- Leftovers can be stored in a sealed container in the fridge for up to 3 days and reheated in the microwave with a splash of water or broth.
Freeze– This is not recommended because pasta does not thaw well.
Make ahead instructions– This recipe can be made 1 day in advance and stored in the fridge. When you are ready to serve, heat in the microwave, instant pot or stovetop with a splash of water or broth (if necessary).

I loved this. So did my carnivore husband. I like the fact that you presented alternatives to the original recipe. I used eggplant (steamed it first), okra and chickpea pasta. Delish.
Threw in some cooked/frozen hot sausage I had in the freezer. Only used half a jar of spaghetti sauce b/c we don’t like our pasta super saucy. Used a splash of half and half at the end. My husband said “don’t be mad if I don’t like this dinner” because he doesn’t like so many things mixed together. After eating he admitted he was wrong and said to definitely make this again. It was so easy and absolutely delicious! I love that I can add whatever veggies I have leftover….including half full bags of frozen veggies.
