This easy crockpot version of our Classic Chicken Tetrazzini is here for you when you’re short on hands. Creamy, cheesy pasta studded with chicken and mushrooms is the ultimate weeknight meal you can throw in the crockpot in the morning, and a mostly hands-off meal will be ready by dinner.
There are lots of ways to modify this recipe if you are looking to shake things up a bit. Try adding spinach and artichoke hearts to the dish for freshness and vibrancy. Crumbled Bacon and peas or broccoli also make great additions, as do sun-dried tomatoes for a Mediterranean flair.

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
