Olive Oil Swaps for Holiday Hosting: Easy Dairy-Free Sides for the Whole Table
Hosting a holiday meal gets simpler when you can serve dishes everyone at the table can enjoy, including guests who avoid dairy or follow a plant-based diet. One of the easiest ways to make that happen? Reach for the bottle of extra virgin olive oil already in your pantry.
A few thoughtful ingredient swaps can make a big difference. Replace butter with olive oil in savory dishes like mashed potatoes and roasted vegetables, and you can create flavorful, dairy-free holiday sides without preparing separate meals. A high-quality extra virgin olive oil brings its own grassy, peppery character to the table while making holiday cooking more versatile.
Whether you're planning Thanksgiving dinner, a Christmas gathering, or a casual holiday get-together, cooking with olive oil makes it easier to welcome everyone to the table.
Can you substitute olive oil for butter in holiday recipes?
Yes! Extra virgin olive oil can replace butter in many savory holiday recipes, including mashed potatoes, roasted vegetables, dressings, and bread dips. As a general starting point, use ¾ cup of olive oil for every 1 cup of butter in savory cooking. Choose a mild or robust olive oil depending on the flavor you want.
How to Substitute Olive Oil for Butter
Cooking with olive oil instead of butter is one of the simplest ways to make savory holiday recipes dairy-free. The key is knowing how much to use.
For most savory cooking applications, start with ¾ the amount of olive oil as the butter called for in your recipe.
- 1 cup butter = ¾ cup olive oil
- ½ cup butter = ⅜ cup olive oil
- ¼ cup butter = 3 tablespoons olive oil
- 1 tablespoon butter = approximately 2¼ teaspoons olive oil
Because butter contains water and milk solids while olive oil is entirely fat, a one-to-one substitution can make certain dishes feel overly oily. Using slightly less olive oil helps maintain a balanced texture while adding its own natural flavor.
This guideline works particularly well for sautéing, roasting, mashed potatoes, and savory sides. Baking is a little different because butter contributes structure and moisture, so adjustments depend on the recipe. For cakes, muffins, and quick breads, olive oil can be an excellent alternative.

4 Easy Dairy-Free Holiday Side Dishes
You don't need an entirely separate holiday menu to accommodate guests with dietary preferences. These four simple California extra virgin olive oil swaps make familiar holiday favorites easier to share:
- A Two-Minute EVOO and Balsamic Bread Dip: Pour good olive oil into a shallow bowl, swirl in a spoonful of aged balsamic, and add flaky salt and cracked pepper. Reach for a grassy, peppery oil like Classic here, since the dip puts the oil front and center. No stove. Set it out with torn bread while you finish the real cooking, and you’ve bought yourself twenty quiet minutes in the kitchen.
- Creamy Dairy-Free Mashed Potatoes: Swap the butter for olive oil at ¾ the amount, then loosen with a little hot potato water or oat milk. A mild, buttery oil like Cucina stands in for butter beautifully, turning the potatoes silky and savory with a faint pepperiness butter never gives you.
- Herb-Roasted Holiday Vegetables: Carrots, brussels sprouts, and squash crisp better when tossed in olive oil than when tossed in melted butter, and you skip the step where butter burns in the pan. A robust oil like Tuscan stands up to the heat and the heartier vegetables. Our notes on Cooking with Olive Oil and Fall Produce cover which vegetables work well with our various olive oils.
- Bright Citrus Vinaigrette: In place of a heavy creamed vegetable, dress shaved fennel or roasted beets in olive oil and vinegar, using a sharp, fruity oil like Citrus to lift the whole plate. It’s the vegan holiday side that cuts through everything richer on the table, and it’s inclusive of most diet restrictions without trying to be.
Why Cook with Olive Oil for Holiday Meals?
The real benefit of these swaps goes beyond the ingredients. When your mashed potatoes, roasted vegetables, and appetizers are already dairy-free, you can serve the same dishes to more guests without preparing separate versions.
One tray of vegetables instead of two. One bowl of mashed potatoes everyone can enjoy. An appetizer that welcomes guests with different dietary preferences without making anyone feel like an afterthought.
Extra virgin olive oil also brings something to the table that many neutral cooking oils cannot: its own distinctive flavor. Depending on the variety, it can contribute grassy, fruity, buttery, or peppery notes that complement the natural flavors of your ingredients.
Not all cooking oils offer the same flavor or culinary experience. If you're curious about how they compare, read our guide to Olive Oil vs Vegetable Oil.
Choosing the right olive oil for the dish makes a difference:
- Mild and buttery: Ideal for mashed potatoes, delicate vegetables, and recipes where you want a softer olive oil flavor.
- Balanced and grassy: Great for bread dipping, dressings, and everyday holiday cooking.
- Bold and peppery: A natural match for hearty roasted vegetables, savory sides, and finishing dishes.
Easy Holiday Appetizers with Olive Oil and Balsamic
A thoughtfully chosen olive oil and vinegar pairing is one of the easiest ways to make holiday entertaining feel special. With minimal preparation, you can create an inviting appetizer spread that gives guests something to enjoy as soon as they arrive.
The trick is matching an olive oil to a vinegar so their flavors complement one another. Herbal and savory notes meet bright, fruity, or sweet flavors for combinations that work beautifully with warm bread, roasted vegetables, and holiday grazing boards.
A few pairings worth setting out this season:
- Rosemary Olive Oil + Fig Balsamic Vinegar. The herbal, piney oil and the sweet-tart fig play beautifully together over warm focaccia or alongside a holiday cheese board.
- Tuscan Extra Virgin Olive Oil + Tuscan Balsamic Vinegar. A robust, peppery oil with a savory-sweet balsamic, made for bruschetta and a grazing board that holds up to bolder appetites.
- Lemon Olive Oil + Aged Balsamic Vinegar. Bright citrus against deep, syrupy balsamic, lovely drizzled over burrata or roasted squash.
Set out one or two combinations when the first guests arrive, and the pressure in the kitchen drops. Guests have something to gather around while dinner comes together, and you can spend less time preparing appetizers and more time enjoying the occasion.
These pairings also make thoughtful gifts for hosts and food lovers. The Holiday Dinner Collection and Season's Savory Greetings Gift Box bring together flavorful olive oils and vinegars that are ready to enjoy.
