Ingredients in this cheesy carrot casserole recipe

Only 12 ingredients are needed for this cheesy carrot casserole recipe, including the spices! Below is everything you’ll need:

  • Carrots: First up is one 4lb bag of large carrots. They should be peeled, halved, and diced into 2 inch chunks.
  • Butter: Next, 1/2 cup of butter is used to cook the onion.
  • Onion: And as for the onion, use 1/2 of a yellow, minced.
  • Garlic: Add flavor with 2 cloves of minced garlic. If powder is preferred, use 1/2 teaspoon ground garlic powder.
  • Flour: Thicken up the casserole by adding 1/4 cup of all purpose flour.
  • Salt & pepper: Salt and pepper is a must. Use 1 teaspoon salt and 1/2 tsp of black pepper.
  • Celery salt: Follow the salt and pepper with 2 tsp of celery salt.
  • Brown mustard: Brown mustard adds a delicious touch of flavor to this recipe! Use 1 tbsp.
  • Milk: 1 and 3/4 cup of milk thickens up the casserole and makes it nice and creamy. I recommend using whole milk.
  • Kraft Old English Cheese Spread: Finally, add the cheesiness with 2 5oz containers of Kraft Old English Cheese Spread.
  • Breadcrumbs: Last but not least, finish off with 1 cup of breadcrumbs.

Tools used to make this cheesy carrot casserole recipe

To prepare this dish, you’ll need a variety of kitchen tools and measuring cups sizes. Before you begin, gather a large pot, cutting board, cutting knife, saucepan, whisk, and a 9×13 baking dish (or slightly smaller).

For measuring ingredients, you will need 1/2 tsp, 1 tsp, 1 tbsp, 1/4 cup, 1/2 cup, 3/4 cup, and 1 cup sized measuring cups.

How to make cheesy carrot casserole

Ready to dive in? You can expect this recipe to require around 25 minutes of prep time and 25 minutes of baking time.

Begin by filling a large pot with water and bringing it to a boil. Once boiling, peel, halve, and slice the carrots into 2 inch chunks and then add them to the pot. Cook for 13-15 minutes, or until fork tender. Drain.

Then, set a saucepan or large skillet over medium heat and add the butter. Once mostly melted, add the onions and cook for 2-3 minutes, or until they begin to soften. Add the garlic and cook for 20 more seconds. Next, whisk in the flour, salt, pepper, and celery salt, and then mix in the brown mustard.

Pour the milk into the flour mixture and stir with a whisk until smooth. Bring to a low simmer and then add the Old English Cheese. Let the cheese melt and bring it to a light simmer, cooking for an additional 5 minutes until the sauce has thickened up.

Pour the tender carrots into a 9×13 inch casserole dish (or slightly smaller). Pour the cheese sauce on top and mix until the carrots are coated. Sprinkle the top with breadcrumbs and bake for 25 minutes at 350°F.

Finally, during the last few minutes, turn the oven to broil to make the breadcrumbs golden brown.

Let cool for at least 20 minutes before serving.

Storing leftovers

If you’re left with casserole leftovers, transfer them to an airtight container and store in the refrigerator for up to 2-3 days. Reheat in the oven or microwave. Adding a splash of milk may help restore some of the lost creaminess that happens during refrigeration.

Recipe Tips

What is in this casserole?

This particular cheesy casserole recipe uses carrots, butter, onion, garlic, flour, salt, pepper, celery salt, brown mustard, milk, Kraft Old English Cheese Spread, and breadcrumbs.

Can I add meat to this casserole?

Though I haven’t tried it, I imagine that ground beef or turkey would work quite well to add extra protein to this casserole. If you try it out, let me know!

Do I have to use carrots?

You don’t have to! If carrots aren’t your thing but you’d still love to try this cheesy casserole, you can use sweet potatoes instead.
