Steps

Before you start

Have fresh lemon and lime juice ready, preferably freshly squeezed just before use
Bring all ingredients to room temperature for best emulsification and flavor blending
Have a shallow glass or ceramic dish ready for marinating the tofu
Choose firm or extra-firm tofu blocks, not silken

1
Prepare citrus base with mustard
- Squeeze fresh lemon juice and fresh lime juice directly into a medium mixing bowl, being careful to strain out any seeds.
- Add the Dijon mustard and stir with a whisk until the mustard is fully dissolved and smooth.
- This citrus-mustard base will be the foundation of your marinade.

Ready when: Mustard is fully dissolved and mixture looks smooth and uniform
Tip: Use freshly squeezed citrus juice for the brightest flavor—bottled juice lacks the vibrant acidity and aromatic complexity of fresh juice
2
Create emulsion with olive oil
- While whisking constantly, pour the olive oil in a very slow, thin stream into the citrus mixture.
- Continue whisking steadily for about 2 minutes as the oil incorporates.
- The mixture should begin to look slightly thickened and more unified, though it may not fully emulsify like a vinaigrette.

Ready when: Oil is fully combined and the mixture looks slightly thickened and creamy
Tip: Adding the oil slowly while whisking constantly prevents the marinade from breaking or becoming greasy—rushing this step results in a separated, less effective marinade
3
Add fresh herbs and garlic
- Stir in the finely chopped fresh thyme, rosemary, and minced garlic into the oil-citrus mixture.
- Mix thoroughly for about 1 minute until the herbs and garlic are evenly distributed throughout, so no clumps of garlic remain.

Ready when: Herbs and minced garlic are evenly dispersed with no visible clumps
4
Season the marinade
- Add the sea salt, freshly ground black pepper, and red pepper flakes (if using).
- Stir well to combine.
- Taste the marinade carefully by dipping a small spoon into it—the flavor should be bright, savory, and well-balanced.
- Adjust salt or pepper to your preference; remember that this marinade is meant to be bold and flavorful.

Ready when: All seasonings are evenly mixed and taste is bright and balanced
Tip: Taste and adjust seasonings now—once the tofu marinates, it will be harder to adjust the flavor balance
5
Prepare the firm tofu
- Remove the firm tofu blocks from their packaging and pour off any liquid.
- Wrap each block loosely in several layers of clean paper towels.
- Gently press each wrapped block for 1–2 minutes by applying light, even pressure; this removes excess moisture that would otherwise dilute the marinade and prevent proper flavor absorption.
- Once pressed, cut the tofu into 3/4-inch-thick slabs, 3/4-inch cubes, or triangles, depending on your preferred shape for cooking later.

Ready when: Tofu is patted dry and cut into uniform, evenly sized pieces
Tip: Pressing the tofu is crucial—it removes moisture that prevents the marinade from penetrating and seasoning the tofu effectively
6
Marinate and refrigerate
- Arrange the prepared tofu pieces in a single layer in your shallow glass or ceramic dish.
- Pour the prepared marinade over all the pieces, ensuring they are evenly coated on all sides; gently stir to coat thoroughly.
- Cover the dish with a lid, plastic wrap, or aluminum foil.
- Refrigerate for at least 4 hours, but preferably 8 hours or overnight.
- The longer the tofu marinates, the more flavorful and complex it becomes.
- Occasionally stir gently or rotate the pieces if they shift during marinating to ensure even exposure to the marinade.

Ready when: Tofu is thoroughly infused with the bright citrus and herbaceous flavor of the marinade
Tip: Marinate overnight or for 8–12 hours for the deepest, most complex flavor. Do not leave marinated tofu unrefrigerated for more than 2 hours

Good to know

Tips

Freshly squeezed citrus juice makes a significant flavor difference—the bright acidity and aromatic oils in fresh juice cannot be replicated by bottled juice, which is often pasteurized and loses complexity
Pressing the tofu properly before marinating is essential; it removes excess water that would otherwise dilute the marinade and prevent the tofu from absorbing the citrus and herb flavors
The longer you marinate, the better. While 4 hours is the minimum for acceptable flavor, marinating overnight (8–12 hours) develops the deep, complex taste this recipe is meant to deliver
Save any leftover marinade in an airtight container in the refrigerator for up to 1 week and use it as a salad dressing, vinaigrette for roasted vegetables, or a dipping sauce

Make ahead

You can prepare the marinade up to 1 week in advance in an airtight container in the refrigerator. Marinate the tofu for at least 4 hours, preferably overnight. Marinated tofu keeps in the refrigerator for up to 5 days in the marinade.

Storage & reheating

Refrigerator: Store marinated tofu in an airtight container for up to 5 days. The flavors will deepen and intensify over time. Freezer: Marinated tofu can be frozen for up to 2 months in an airtight freezer container. Thaw completely in the refrigerator before cooking. Room temperature: Do not leave marinated tofu at room temperature for more than 2 hours. To reheat or cook: Pan-sear thawed marinated tofu in a hot skillet, grill, bake at 400°F (200°C) for 20–25 minutes, or add to stir-fries.

Substitutions

fresh thyme → Dried thyme (use 2/3 tablespoon or 1 teaspoon dried for every 2 tablespoons fresh). Dried herbs are more concentrated than fresh. Add them in step 3 as directed. The flavor will be less bright, so consider adding an extra squeeze of fresh lemon juice to compensate
fresh rosemary → Dried rosemary (use 1 teaspoon dried for every 1 tablespoon fresh). Dried rosemary has a more intense, piney flavor. Use sparingly and taste as you go
fresh lemon juice → Other citrus juice (fresh orange juice, grapefruit juice, or a blend with lemon). Using different citrus will shift the flavor profile. Orange will be sweeter and less tart; grapefruit will be more bitter. A mix of citrus juices can add complexity
extra virgin olive oil → Neutral oil (grapeseed oil, vegetable oil, or light avocado oil). Neutral oils work but lack the fruity depth that extra virgin olive oil provides. The marinade will be less flavorful but will still work well
