Overnight lettuce salad is my grandma's 7 layer salad made with lettuce, cauliflower, mayonnaise, onions, celery, bacon, and parmesan cheese. This salad is always a favorite at family gatherings. It makes a huge amount of salad, so you will want to cut it in half if you are making it just for your family of four or five people. It can be made sweeter with a little sugar but without it is a perfect low-carb salad as well.
This salad is one of those that you can also alter. Want to add peas? Go for it. Would hard-boiled eggs work in this salad? Absolutely! Can regular onions be substituted for green? Sure. The concept of layering and leaving until you are ready to eat and then tossing is what makes this overnight lettuce salad one of my favorite seven-layer salad recipes.
7-Layer Salad Ingredients
To make this salad you will need to have fresh ingredients either whole or prechopped. Here is what the bowl of ingredients looked like for the overnight salad.
- Lettuce - Romaine is my preference by iceberg will work also
- Cauliflower - Whole head of fresh cauliflower. Frozen is not recommended.
- Mayonnaise - Miracle whip will also work, but omit the option sugar if you use Miracle Whip
- Green onions - sweet onions will work as well if you don't have green onions on hand.
- Celery - This can be left off if you don't dig celery
- Bacon - Fried and crumbled. You can also buy the prepackaged bacon bits or crumbles. I prefer freshly fried bacon
- Parmesan cheese - Grated works perfectly for this salad but shredded can also be used if it is your preference.
Optional Ingredients for 7-Layer Salad:
- Hard-boiled eggs
- Shredded Colby-Jack or Cheddar Cheese
How to Make Overnight Lettuce Salad with Cauliflower
The hardest part of this salad is chopping everything up for the various layers. You will simply place the chopped lettuce in a large low profile bowl or 13X9 dish. Follow this with the chopped cauliflower and the finely chopped celery. Then spread the mayonnaise over the lettuce, cauliflower, and celery.
The next steps of the 7-layer salad are to take the chopped up green onions and layer them over the mayonnaise. The green onions are easily cut with kitchen sheers directly over the top of the mayonnaise. Then comes the bacon crumbles. The infamous black bag of bacon crumbles works. But, I like freshly fried bacon and use the packages of scrap bacon I have been getting from Sam's club. Normal sliced bacon will work just fine too. Layer the bacon on top of the green onions.
Then spread the parmesan cheese over the top of the bacon and onions. Now, if you want a slightly sweeter salad, add sugar. But, grandma's 7-layer salad always left it out. It will be just fine with it. Cover the salad with plastic wrap and refrigerate overnight or until you are ready to eat.
- While I make this salad with cauliflower it can also be made with fresh or frozen peas or even broccoli.
- If you do not like celery, leave the celery out.
- Can Miracle Whip be used instead of mayonnaise? Yes, absolutely Miracle Whip can be used to make the 7-layer salad. I would definitely omit the sugar with Miracle Whip since it is already sweeter.
- Can the leftover overnight salad be saved? I definitely eat this salad for up to two days after it is originally served.
