Yams are more starchy than sweet potatoes, they are much more like regular potatoes in texture, so they are best avoided for this recipe, though you can use them in a pinch.

This Essential Grocery List is an absolute life saver for my family on the busy weeks. When I started this journey to learn how to cook, I quickly realized that the first step in cooking is having staple ingredients on hand. I want to avoid having to run out to the grocery store every single time I prepare a new recipe. Having a well-stocked pantry has made my life in the kitchen so much simpler, because when it’s time to cook, I have what I need.

Essential Grocery List
It’s so helpful to have a basic grocery list to help me remember which foods to buy at the store. This food shopping list is my go-to!
It’s better to stock up on things like grains, seasonings and spices, baking essentials, oils, condiments, canned and frozen foods, etc. so I can just grab them when I need them. These things have a long shelf life , so I keep them in my kitchen for convenience.
However, I do have to go to the supermarket sometimes, and there’s a way to make that trip easy and hassle-free: I keep a grocery list! If I go in blindly, I’ll leave with things I don’t need, and nothing that actually helps me prepare a good meal.
In the list below, I’ve compiled everything I always have on my stock-up grocery list.
I’ve got you covered! I created an easy grocery list filled with all of the essentials. Plus there’s a free printable version that you can take with you to the grocery store. It has everything you need to stock your pantry, your freezer, and your refrigerator.

What to Buy at the Grocery Store
This is the perfect grocery list filled with all the basics and essentials. It should help get you going if you’re new to cooking, or if you’re just left staring helplessly at an empty pantry and don’t know how to fill it.
When I first started cooking, things could seem overwhelming. I quickly realized that they more prepared I could be, the more confident I felt. If you already have the basics in your kitchen, then you can shop stress-free.
So print out our easy grocery list, stock up your pantry and fridge, and you’ll be cooking in no time!
