Make-Ahead Chicken Broccoli Alfredo in a Jar (No Canning Required!)

What if I told you that you could have a creamy, restaurant-quality chicken Alfredo on the table in under an hour—with most of the work already done weeks in advance?

No freezer space needed. No canning equipment required. Just simple dehydrated ingredients layered in a jar, ready to become dinner whenever you need it.

This chicken broccoli Alfredo in a jar is going to be featured in our upcoming Mix in Jars Volume 2 cookbook. And today I’m walking you through exactly how to make it.

Why Meals in Jars Are a Game-Changer

Before we jump into the recipe, let me tell you why I’m obsessed with this method.

Traditional freezer meal prep is great, but it has some serious limitations. You need dedicated freezer space (which I never seem to have enough of).

You’re dependent on your freezer not going out. And if you lose power? You’re in trouble.

Dehydrated meals in jars solve all of that. They sit happily on your pantry shelf for months. They don’t take up precious freezer real estate. And honestly? They’re just as quick to prepare as pulling something from the freezer.

We typically prep 4-5 jars at a time in our house. That’s how we roll with meal prep—jars, not freezer bags. It takes maybe 20 minutes to assemble multiple jars, and then future-you gets to enjoy the benefits for months.

What You’ll Need for the Jar

This recipe makes just over 4 cups, which fits perfectly in a quart jar with a little creative layering.

Dry Ingredients:

• 3 cups pasta (rotini, penne, or whatever you have on hand)
• 1 cup dehydrated broccoli
• 2 teaspoons dried minced garlic (I always do a heaping scoop)
• 1 teaspoon onion powder
• 1 teaspoon Italian seasoning (or oregano if you don’t have the blend)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 tablespoon nutritional yeast

For Cooking:

• 6 cups water
• 4 tablespoons butter
• 4 tablespoons flour
• 3 cups cooked chicken (canned, home-canned, or rotisserie—your choice)
• 2 cups freshly shredded Parmesan cheese
• 1 cup heavy whipping cream

How to Layer Your Jar

Here’s the trick to making everything fit: solids first, powders on top.

Start with your 3 cups of pasta. I used rotini because I had a box sitting in my pantry that needed to be used up, but penne is my usual go-to. Just fill to the 3-cup mark on your quart jar—we’re not going for NASA-level precision here.

Next, add 1 cup of dehydrated broccoli. Give the jar a good shake to settle everything down. Push it down gently so it fills right up to the top.

Now for all your seasonings. Add them in this order: 2 teaspoons minced garlic, 1 teaspoon Italian seasoning, 1/2 teaspoon salt, 1/4 teaspoon black pepper, 1 teaspoon onion powder (don’t forget this one like I almost did!), and 1 tablespoon nutritional yeast.

The nutritional yeast adds this wonderful cheesy, slightly nutty flavor to the Alfredo sauce. If you’ve never used it before, trust me on this one.

Give the jar one final shake so all those seasonings scatter down into the pasta. Seal it up, label it with the date, and you’re done.

How to Cook It

When you’re ready to eat, this becomes a one-pot meal.

Pour the entire contents of your jar into a large pot. Add 6 cups of water—that’s a bit more than usual because of the dehydrated broccoli.

Bring everything to a boil. This takes about 20 minutes. Once it’s boiling, give it a stir to scrape any seasonings off the sides, then reduce to a simmer. Cover and cook for 20 minutes.

In the last 5 minutes of simmering, take the lid off to let some water evaporate. You want most of the liquid gone, but not all of it.

Now here comes the magic part. Keep your heat around medium (4-5 on most stoves). Add 4 tablespoons of butter and 4 tablespoons of flour. Stir that together until the butter melts.

Add your 3 cups of chicken. Now, just being real here—sometimes I really need to stretch meat and I’ll only use 2 cups or even less. The pasta is filling enough that nobody really misses it. But right now I don’t need to stretch meat, so I’m using the full 3 cups.

Let everything bubble slightly, then add 2 cups of freshly shredded Parmesan. Please use the real stuff, not the powdered kind in the green can. It makes such a difference.

Finally, stir in 1 cup of heavy whipping cream. Give everything a good mix and let it heat through until the cheese is melted and the sauce has thickened.

That’s it. Dinner is done!

Making This Your Own

This is the base recipe, but you can absolutely customize it:

• Use less chicken to save money (2 cups works great)
• Swap the broccoli for dehydrated spinach or peas
• Add dehydrated mushrooms to the jar
• Use whatever pasta shape you have on hand
• Make it spicier with red pepper flakes

The beauty of meals in jars is that once you understand the method, you can adapt it to what you have and what your family actually eats.

Meal prepping doesn’t have to mean spending your entire Sunday cooking or dedicating half your freezer to plastic containers.

Sometimes the smartest meal prep is the kind that sits quietly on your shelf, ready to rescue dinner on those nights when everything goes sideways.
